Justin Bieber's personal Instagram may be more effective than the Multiple Listing Service in moving real estate ... because his one post declaring he's in the market to sell his house has generated tons of interest ... including from at least one billionaire.

Bieber -- who boasts an insane 120 million followers on IG -- casually mentioned last week he's looking to sell his Beverly Hills home ... "I'll sell it with all the furniture. MAKE AN OFFER."

Sources with direct knowledge tell TMZ ... Justin's been contacted by at least 5 prospective buyers ... either directly or through their realtors. We're told one of the prospective buyers is a billionaire from a very famous family.

Justin and Hailey bought the 6,132-square-foot property last year for $8.5 million. A highly respected real estate agent in L.A. tells us the home isn't worth more than that -- but says there are certain buyers who will pay a premium because of the current owner. He says that the buyer would probably offer somewhere in the 9's.

The house has 5 bedrooms, 7 bathrooms and a sunken family room design. It's also got a home theater, wine cellar and a massive kitchen.

Jennifer Aniston just joined the world of Instagram by reminding everyone some of her best friends are their "Friends." Translation: First class clout chasing!

Jen created her first account Tuesday morning on the social media platform, and her first post was a pic of herself hanging out with Lisa Kudrow, Courteney Cox, Matt LeBlanc, David Schwimmer and Matthew Perry.

It's unclear where or when the photo was taken, but Aniston was on Howard Stern's show last week and mentioned that she and her former costars were able to grab dinner together recently ... so it might be from that outing.

Jen captioned her pic, "And now we're Instagram FRIENDS too. HI INSTAGRAM."

The weird thing is her account was temporarily taken down after being live for less than an hour, but it's up and running again. A few notable stats ... she's already over 120k followers, and she's following her ex, Justin Theroux.

It appears Aniston commented on LeBlanc's most recent IG post, too ... which was a 1994 cast photo he shared last month in honor of the 25th anniversary of the "Friends" premiere.

Jen wrote ... "You don't have to # me anymore."

DMX decided to be proactive in his battle with addiction before it led to another relapse -- and potentially more legal trouble -- so that's why he's back in rehab.

Sources close to the rapper tell TMZ ... one of X's kids is very sick -- in and out of the hospital -- and the stress of that coupled with the pressure of performing again made him feel tempted to use.

We're told X knew he needed help trying to balance his home and work life without the use of drugs, so he preemptively checked himself into rehab -- hoping to learn how to deal with his issues moving forward.

Our sources say he knows a relapse could jeopardize his freedom, and wants to stay out of jail so he can support his family and friends -- while still performing for his fans.

DMX is on probation and gets tested randomly for drugs and alcohol ... so another failed test could result in him back behind bars.

As we reported ... the rapper canceled a couple of gigs this weekend after announcing he checked himself into a rehab facility, and was putting his family and his sobriety first.

DMX has struggled with addiction for many years and has been jailed numerous times for drug-related offenses, and has been in and out of rehab.

He was released from prison in January after serving time for tax evasion.

Enes Kanter has a message for LeBron James -- "FREEDOM IS NOT FREE."

Moments after LeBron broke his silence on the situation with China, the Turkish-born Boston Celtics player went to Twitter to express his disgust, as illustrated by the green "sick face" emoji.

Oh, and when LeBron pointed out that he and his team had a "difficult week" dealing with the fallout of Daryl Morey's pro-Hong Kong tweets while the Lakers were in China, Kanter essentially had this to say to Bron, "Boo hoo!"

Actually, Kanter -- who's spoken out against the Turkish government for years -- spelled out to LeBron all of the things he's sacrificed to put a spotlight on the injustices and atrocities he feels are taking place in his home country.

"Haven’t seen or talked to my family 5 years," Kanter noted ... while also pointing out the Turkish government has jailed his father, revoked his passport, issued an international arrest warrant and more.

Kanter says he's received death threats daily and was the target of a kidnapping attempt in Indonesia.

While Kanter never mentioned LeBron by name in his tweets, it's pretty obvious he was trying to send a message Bron's way.

Wanna buy the house that sits on the lot where John Wayne Gacy murdered 33 people??? Not exactly genius marketing, sure, but the pad's hit the market and it's getting a lot of buzz.

The house, where police made the grizzly discovery of 29 rotting bodies back in 1978, was bulldozed a year later. Seven years later, a new house was built on the lot. It's a modest home and there's not a hint of the horror that preceded it.

The 3-bedroom, 2-bathroom house is in the Chicago burbs. It's 2,500 square feet and the lot itself is just under 9,000 square feet. It's going for $459k.

It's marketed as a "beautiful brick home" with an updated kitchen that overlooks a huge backyard. It's been dubbed a must-see house. No mention of its connection to one of America's most prolific serial killers.

In Illinois, the murders don't have to be disclosed, but if a prospective buyer asks about it the realtor must be honest.

Gacy -- executed by lethal injection in 1994 but whose brain is shockingly a hot item -- killed 33 boys and young men in the 70s. He buried 29 of his 33 victims in the trenches underneath and around his home and dumped four others from bridges once his property couldn't hold any more bodies.

After the house was razed in 1979, the vacant lot drew hoards of gawkers ... fans, documentarians and even ghost hunters. A Chicago woman bought the land in 1986 for $30,544 and built the house for her retiring parents, who apparently knew what had gone down on the property.

One of Captain Wild Bill's former deckhands on Cape Caution just went overboard with the law -- getting busted for drugs, which cops believe to be heroin.

33-year-old Jerod Sechrist was arrested in Tampa, FL on drug charges -- specifically felony possession of heroin and misdemeanor possession of drug paraphernalia.

According to the police report, obtained by TMZ, cops say they arrested Jerod on an open warrant last week for a previous reckless driving case. When they took him to the station at around 3:00 AM, officers say they found a small clear bag in his pocket with a white powder substance inside.

Police say they did an in-house test on the spot, and the results came back positive for heroin.

Jerod appeared in 3 episodes in 2016 but was memorable for having a hard time differentiating between male and female king crabs. He continually pissed off his crewmates due to the potentially costly mistakes, because it's illegal to catch females.

Tito Ortiz's love for the Trump family is definitely mutual -- with the UFC legend getting invited to hang with the President after a private lunch with Don Jr. and Eric Trump.

Tito's camp tells TMZ Sports ... Eric personally reached out to Tito last week when he heard the MMA superstar was in New York -- and the two sides quickly arranged a lunch date at Trump Tower.

"Secret Service walked us through crowds to a private room in Trump's restaurant," Tito's rep tells us.

"They talked fights and politics before Donald Jr. came down to join before heading off to a campaign event."

TMZ Sports obtained footage of the meeting which shows the guys chumming it up together and giving all sorts of Trump swag to Ortiz.

Tito and the Trumps go wayyy back -- Tito appeared with Donald on "Celebrity Apprentice" in 2008. Plus, Dana White has previously credited Donald for helping to take UFC to the next level when other hotel and casino owners were giving the company the cold shoulder.

The Trumps are big fight fans -- they recently had VIP seats to watch Colby Covington beat down Robbie Lawler at a UFC event in New Jersey.

During lunch, we're told Tito invited the whole family to his Dec. 7 fight against former WWE champ Alberto Del Rio (aka Alberto El Patron) and we're told the guys are going to try and make it work with their schedules.

Staten Island-local Mike Giannelli is best known for playing the creepy Art The Clown -- who terrorizes, tortures and murders young people on a VHS tape -- in the 2013 killer clown film "All Hallows' Eve."

Mike Giannelli is cemented into the ranks of classic homicidal clown movies including "Killer Klowns From Outer Space," "Poltergeist," 2019's "Joker" and of course Stephen King's "IT."

Freaky fact: Mike Giannelli did not take on the role of Art The Clown in the 2016 fright follow-up, "Terrifier," instead the clown was played by David Howard Thorton.

LeBron James is FINALLY talking about the Daryl Morey tweet that sparked an international incident ... saying the Rockets GM simply "wasn't educated" about China before he posted his pro-Hong Kong tweet.

"I think that's another situation that should stay behind closed doors," LeBron told the media.

Remember, LeBron and the Lakers were in Shanghai to play the Brooklyn Nets in an exhibition game last week when the backlash over the tweet began.

Chinese officials essentially blackballed the Houston Rockets immediately -- taking down signage, pulling merchandise and blocking TV networks from airing games.

But, now LeBron is back in the U.S. ... and he's calling out Morey for what LeBron is describing as a selfish tweet.

"We all talk about this freedom of speech. Yes, we all do have freedom of speech, but at times there are ramifications for the negative that can happen when you're not thinking about others and you're only thinking about yourself," LeBron said.

"I don't want to get into a word or sentence feud with Daryl Morey but I believe he wasn't educated on the situation at hand, and he spoke. And, so many people could have been harmed, not only financially but physically, emotionally, spiritually. So, just be careful what we tweet and what we say, and what we do. Even though yes, we do have freedom of speech, but there can be a lot of negative that comes with that too."

When questioned about why he thinks Morey -- who had tweeted out "Fight For Freedom. Stand with Hong Kong" --  is uneducated, LeBron had this to say:

"That's just my belief. I don't know. That's my belief. That's all I can say. I believe he was either misinformed or not really educated on the situation."

"And, if he was, then so be it, but I have no idea. That's just my belief that when you say things or do things and you know the people can be affected by it, and the families and the individuals and everyone that can be affected by it, sometimes things can be changed. And, also sometimes social media is not always the proper way to go about things as well. But, that's just my belief."

After LeBron made the comments, there was immediate backlash on social media from people upset with his comments. LeBron went to Twitter to defend himself.

"Let me clear up the confusion," LeBron said ... "I do not believe there was any consideration for the consequences and ramifications of the tweet.  I’m not discussing the substance.  Others can talk About that."

The white cop who shot and killed Atatiana Jefferson in her own home over the weekend is sitting in a jail cell right now ... this after outcry from the community.

Former Fort Worth police officer Aaron Dean was booked on a murder charge Monday, according to online records from the Tarrant County Corrections Center. It appears Dean is still in custody as of this writing -- with his bail set at $200,000.

It's unclear how exactly he was taken into custody, but Dean's arrest comes hours after he turned in his resignation ... and reportedly refused to cooperate with the investigation. This all comes after he gunned down Atatiana -- a black woman -- while in her own home.

Dean was responding to a welfare call at around 2:30 AM Saturday after a concerned neighbor said they saw her door open. In body cam video released by the Forth Worth Police, you see an officer -- reported to be Dean -- creep up to a window in her backyard ... and almost instantly fire a shot after seeing Atatiana approach from inside.

He quickly told her to put her hands up, but barely gave her any time to respond ... and he also did not identify himself as a police officer. Atatiana was reportedly playing video games with her 8-year-old nephew in the house ... again, her own property.

She succumbed to her wounds and died in her bedroom.

Of course, the city of Fort Worth was outraged by the killing ... with even the Mayor calling for justice over the situation. In an open letter, Betsy Price apologized to Atatiana's family and demanded answers from the Police Department.

The cat's outta the bag -- Zoe Kravitz is playing Catwoman in the new 'Batman' movie ... which is interesting, considering she was allegedly too "urban" for Christopher Nolan's take.

The news broke Monday, with multiple outlets reporting that Zoe had landed the role after testing out some scenes last week opposite heartthrob Robert Pattinson -- who's donning the cowl next in Matt Reeves' "The Batman" ... which is hitting theaters in 2021.

The ironic thing about Zoe's casting here is that she told Nylon back in 2015 that she couldn't even get an audition for Nolan's last Batman flick, "The Dark Knight Rises," which she attributed to her race. That's not out of the clear blue sky either.

Zoe said she was basically blocked from even reading for a small role in the movie, allegedly being told that somebody had said they weren't "going urban" with the last installment.

It's unclear what exactly that even means, or what role Zoe was trying to nab at the time -- but this has gotta be the ultimate revenge, right??? BTW, Anne Hathaway played Catwoman in Nolan's version -- but there have been a couple of black women who've portrayed the character.

Perhaps most famously, Halle Berry played Catwoman in the self-titled 2004 flick. Another actress was Eartha Kitt, who played Catwoman in the old "Batman" TV series from back in the '60s. She starred opposite Adam West ... which was pretty groundbreaking in those days.

Now, it looks like Zoe's gonna have a crack at the role -- and, based on what we've seen from her over the years in the drama department, she'll probably kill it.

Cuba Gooding Jr. is now being accused of another incident of sexual misconduct -- the 5th such allegation -- and he's going to face a new charge for it, this week in court.

Law enforcement sources tell TMZ several other women have recently come forward to make new allegations of sexual misconduct against Cuba. We're told one of them is a woman making a claim about Cuba from October 2018.

While the D.A.'s kept details of the allegation under wraps ... it's expected to come out Tuesday when Cuba is arraigned on a new charge. Cuba's attorney, Mark Heller, tells us his client will plead not guilty.

Heller also says the new accuser never pressed charges immediately following the incident, and he claims she only came forward after seeing Cuba's arrest this year. He further claims, her attorney tried to settle the case, but Cuba "declined to be shaken down."

We're told cops are also investigating 3 other alleged incidents -- from 2008, '13 and '15 -- but there are no charges, as of now, related to them.

Of course, Cuba pled not guilty to his original sexual abuse charge, back in June. He's been leaving court with a smile all throughout his case.

TMZ obtained surveillance video from the night in question from the previous incident -- and while it appears Cuba made contact with the woman ... he and his camp have insisted he reached up to touch her hand, and NOT her breast as she claims.

Cuba had also asked the judge to toss his case completely, as he felt his accuser had a "warped mental state" based on previous blog posts and writings of hers.

Ice Cube says he knows how the L.A. Dodgers can finally stop choking in the playoffs -- SIGN MORE BLACK GUYS!!!

He's not joking ... we spoke with Cube (briefly) about the Blue Crew's habitual crashing and burning in the MLB playoffs and the rap legend summed it up this way.

"They need to get some black ballplayers."

We checked out the Dodgers roster ... and yeah, they're definitely lacking when it comes to black players.

Of course, the Dodgers have African-American representation in the upper ranks -- including manager Dave Roberts and co-owner Magic Johnson ... but Cube wants to see more black players on the field.

The Dodgers have been MONSTERS during the regular season for the past few years -- and made it to the World Series in 2017 and 2018 ... but choked it away both times.

Netflix and "When They See Us" creator Ava Duvernay are being sued over the police interrogation technique depicted in the film because its creator claims the movie got his method all wrong.

A former cop named John Reid claims in his lawsuit ... the Emmy-winning film defamed him by saying his method was used to squeeze statements out of the Central Park 5 suspects.

In particular, he points out a scene from episode 4 where a detective and someone from the D.A.'s Office are discussing the interrogation of the suspects. The prosecution staffer says to the detective, "You squeezed statements out of them after 42 hours of questioning and coercing, without food, bathroom breaks, withholding parental supervision. The Reid Technique has been universally rejected. That's truth to you."

In the lawsuit, Reid says the technique he created specifically does not teach withholding parental supervision, denying interview subjects any of their rights or making threats of physical harm. He claims it specifically calls for extra caution when interviewing minors.

In the docs, obtained by TMZ, Reid questions Duvernay saying, "We did our research" before making the film by inviting law enforcement personnel to discuss the case. Reid claims if that were true -- Ava would have learned his technique disavows the type of things depicted in the movie.

He believes the filmmakers deliberately "fabricated a scene designed to broadcast to the audience a conversation they made up that included false statements as to the Reid Technique."

He goes on to defend the Reid Technique, saying it's widely used by law enforcement ... and calls for a structured interview and interrogation process that consists of three stages: fact analysis, investigative non-confrontational interview and interrogation.

According to the docs, Reid says his method is anything but "universally rejected." He says he's conducted more than 6,500 seminars and trained more than 200,000 people to use it, since 2002.

Reid says he demanded a retraction in July ... 2 months after the series was released, but Netflix refused. He's now suing Netflix and Ava for defamation and wants the series to turn over a chunk of the profits, and other damages.
