CELEBRITY JUSTICE ™

Abby Lee Miller has a big fight ahead of her, because her recent health struggles are believed to be related to cancer ... TMZ has learned.

A rep for Miller's doctor, Dr. Hooman Melamed, tells us ... her emergency back surgery Tuesday was to alleviate what he thought was an infection in her spine, but after doing some tests -- he now believes she is suffering from Burkitt Lymphoma ... a form of non-Hodgkins lymphoma.

We're told further testing is needed to confirm the cancer, but she should know for sure in the next day or 2. Regardless, Miller's doc says she'll need another spinal surgery, but is resting comfortably after her first operation.

When we last saw Abby ... she was leaving the halfway house where she is serving the rest of her sentence for fraud to get medical treatment. She was visibly upset and appeared to be in pain.

She's scheduled to be released from the halfway house May 25.

Orlando Brown is back on the outside, and he's got himself nice new duds, too ... all 'cause he was bold enough to ask a random dude near the jail to give him the suit off his back.

TMZ has obtained video from just minutes after Orlando was released from L.A. County Jail Tuesday after a warrant hearing, when we're told he saw two dudes -- Kelvin Asiedu and Raptographer -- doing a photo shoot down the street ... and asked one of them for his outfit -- literally, the one the guy was wearing.

Sure enough, the guys recognized Orlando from his Disney days and happily obliged. Surprisingly, the suit fit ... albeit, it did take a little time to get the pants on.

As we reported ... Orlando was arrested by a bounty hunter in Vegas last week and extradited to L.A. based on outstanding warrants for his arrest. The entire ordeal was pretty dramatic, to say the least ... with Orlando being found in a closet in his underwear.

Rosa Salazar -- who's starring in the upcoming James Cameron/Robert Rodriguez blockbuster "Alita: Battle Angel" -- has one less real-life battle to worry about ... TMZ has learned.

Court sources tell us ... Rosa squared off against her ex-boyfriend, Sam Setzer, and his lawyers Wednesday in front of a judge over claims he made last month that she harassed and threatened him after a breakup.

We're told the judge heard both sides and decided to dismiss the case and toss the restraining order Setzer had gotten against Rosa. The judge said there were no grounds for it.

4/20 6:56 AM PT -- A rep for Calvin tells us, "The claims filed against Calvin Harris are absurd and without merit. We are confident that the Court will dismiss the frivolous lawsuit."

Calvin Harris is being sued by a blind man who claims the DJ screwed him over in a super-expensive home deal.

Harry Moscatel claims he leased Harris' home above the Sunset Strip in West Hollywood last year for $35,000 a month. He put down a $70,000 security deposit and moved in ... according to the docs.

Moscatel's attorney, Scott Doonan, tells us ... the house had problems from the beginning, including hot water and heating issues, faulty doors and a sound system that never worked right.

We're told Moscatel and his family bailed on the home, and he now claims the lease agreement was invalid ... in part because he's a 79-year-old blind man and protected by the Americans with Disabilities Act. The lawsuit does not explain why his disability would allow him out of the lease.

The house was once the love nest of Calvin and Taylor Swift when the 2 were an item.

Moscatel makes other technical arguments about the lease and is asking a judge to declare it null and void. He's also preparing to sue Harris to get a portion of his rent and his security deposit back.

BTW ... Moscatel made news last year after a hoverboard caught fire and burned his multi-million-dollar mansion down. Presumably, that's why he rented Calvin's pad.

We reached out to Calvin's people, so far no word back.

Ex-Playmate Karen McDougal is clear to spill the beans about her alleged affair with Donald Trump ... and, perhaps most importantly to her, make a ton o' money off it.

McDougal had sued the National Enquirer's parent company, American Media, over a non-disclosure agreement she signed with them in 2016. She got $150k and some promotional perks, and the Enquirer got her exclusive story about the 2006 affair with Trump. She sued to get out of the deal.

Well, they reached a settlement ... according to the New York Times, and is now allowed to talk all she wants about her Trump relationship. You'll recall, McDougal sat down with Anderson Cooper last month for a CNN special.

So, why does the settlement matter? It's pretty clear based on the terms, which include American Media getting $75k of any future profits Karen makes off selling the Trump story.

Matt Mantei allegedly pushed his wife and threw her to the ground during a fight over a cell phone -- before being arrested for domestic violence ... according to an incident report obtained by TMZ Sports.

We broke the story ... Mantei was arrested for assault and battery in Michigan on Tuesday night. According to the report, Mantei and his wife of 3 months were at home when they began arguing.

In the report, Mantei's wife claims he "grabbed her forearms and threw her to the floor" after trying to grab her phone. Once on the ground, Mantei allegedly got on top of his wife to prevent her from moving ... and squeezed her hands, causing minor injuries to her fingers.

Once Mantei let his wife go, the report says he began "throwing items around the house and tearing things off the wall."

Mantei's wife called 911 and waited for cops to arrive. The report says she had "visible cuts and bruises to her right hand ... and both hands were somewhat swollen."

M.M. appeared in court this afternoon and pled not guilty to misdemeanor domestic violence ... before being released from jail.

He's due back in court next month.

Mobb Deep's huge success in the rap game came at the expense of the group's managers ... according to a massive lawsuit.

Buck 50 Productions says they managed the careers of Prodigy and Havoc from 2010 until Prodigy's death last summer -- and over that period the rappers racked up a serious tab. In the suit, Buck 50 says their team booked touring, recording and endorsement deals. They also paid advances to Mobb Deep ... for which Buck 50 was never reimbursed, they say.

Total cost for services rendered, according to the suit -- at least $500,000.

Stormy Daniels' team has been flooded with tips on who her threatening mystery man might be less than 24 hours after she revealed the sketch, but she can't say she's that much closer to finding him.

Stormy's lawyer, Michael Avenatti, tells TMZ her legal team has received well over 1,500 tips on potential leads for ID'ing Stormy's alleged perpetrator. However, he says they've only deemed a couple hundred or so credible enough to pursue.

Avenatti wouldn't elaborate on what differentiated credible versus non-credible tips -- but we can take a guess. TONS of people took to Twitter Tuesday after Stormy revealed the sketch on "The View" to compare it to a bunch of celebs ... most notably, Tom Brady. Some even think it looks like Stormy's husband.

As for the legit leads ... Avenatti says Stormy's team has dedicated 40-60 man hours so far running them down. He says they have people on the ground in Vegas, CA and NY.

Randy Orton's tattoo artist is suing WWE and 2K Games -- the company behind WWE 2K18 -- claiming they used her designs without permission.

The woman behind the suit is Catherine Alexander -- a tattoo artist from Illinois -- who says she's been tattooing Orton going back to '03 ... and owns the copyrights to the designs.

Problem is, according to Alexander, Orton is depicted in the video games to a tee -- tattoos included -- and she says that's copyright infringement.

The artists claims she raised the issue with WWE in 2009 ... and was offered $450 for the rights to use the designs.

She says she declined the offer.

As for the tats in question ... Alexander says she gave Orton a tribal tattoo on his upper back ... as well as full sleeve with everything from a Bible verse to a dove, skulls and a rose ... among others.

FYI -- this ain't the first time we've seen a suit like this ... LeBron James' tattoo artist sued 2K last year ... making a similar claim.

Dr. Laura Schlessinger stiffed the accountants that handled her taxes for years -- to the tune of $71k -- and they want her to pay up ... according to a new suit.

Accounting firm Weinberg & Co. claims it provided tax and accounting services for Dr. Laura from February 2009 through January 31, 2016.

According to the docs ... Dr. Laura racked up a bill for $71,013 over that time and has refused to make good.

Travis Scott is firing back at the promoter who sued him for bailing on a Super Bowl weekend concert, while keeping the dough he'd been paid ... TMZ has learned.

Travis filed a response to PJAM's lawsuit against him, but also filed his own countersuit against the company. According to the docs, Travis says the promoter never sent him a confirmed travel itinerary for the Minnesota show. He says right up to Feb. 3, the scheduled day of the show, he hadn't received the travel plans.

In his suit, Travis says he learned PJAM lacked the cash to cover his transportation or the remaining money he was owed for the performance. He admits they did pay him $150k in advance.

Travis is also pissed because he believes someone from PJAM spoke to TMZ about his gig ahead of time. He says that's a violation of the confidentiality agreement both sides signed for the show.

Sources close to Travis had told us at the time he canceled due to weather and logistics, but PJAM thinks he flat-out "refused to show up to the event."

PJAM was suing to get its money back, and damages. Travis is suing to get the additional payment he never got.

Travis' attorney, Howard King, tells us PJAM's lawsuit is “An obvious effort to shake Travis down and avoid the consequences of their breaches. Instead of pursuing a misguided attempt to spin the narrative and salvage their tattered reputation, the responsible step would have been for PJAM to pay Travis the balance of his fee and move on to their next opportunity."

He adds, "Travis apologizes to any fans who were duped by these "wannabe" promoters -- Alex Martini, Jefferson Agar and Patrick Johnston -- into showing up at the cancelled show even after the promoters failed to take the steps to get Travis there.”

Kodak Black got some good news while sitting in his jail cell that will help him get out much sooner than expected ... TMZ has learned.

The rapper's attorney, Bradford Cohen, tells us 2 remaining charges from the January raid of his Florida home have been dropped. The charges were for marijuana possession and possession of ammunition.

We're told Kodak admitted 2 other probation violation charges -- driving with a suspended license and associating with people engaged in criminal activity. He'll get credit for time served, which puts him in line for an October release with good behavior.

Once the rapper's free, the remaining year of house arrest and 4 years of probation will be wiped from his slate ... according to Cohen. He adds, "Kodak [and I] are extremely happy to resolve this case with an excellent resolution. It was very nice to deal with a fair judge who understood the circumstances -- along with prosecutors."

Russell Simmons says the vile allegations against him in a lawsuit filed by Jane Doe are pure fiction, and an extortion attempt to extract money from a rich man.

Simmons filed new legal docs in the case where a woman claimed he raped her after meeting her at a concert. Simmons says in the docs, obtained by TMZ, the suit is an attempt "to extort large sums of money from Mr. Simmons and for her lawyer to try to make a name for himself.

Russell calls the lawsuit "a work of pure fiction." But he says there's a more fundamental reason why the case should be tossed. He notes the woman claimed the alleged rape occurred in 1988 ... and the statute of limitations has long since run on any such claim.

As we reported ... Jane Doe claims she met Simmons at a hip-hop concert she was at with her elementary school-aged son, and ended up at his hotel room later that night after she dropped off her kid. She accused Simmons of threatening her son when she rejected his advances, then threw her on the bed and raped her. She's suing for $10 million.

Ice Cube's got a message for the Qatari investors he's suing for over $1 BILLION ... after they allegedly went back on their agreement with the BIG3.

"We gon’ win. Stay out of American sports if you don’t wanna do the right thing," Cube said on his way into Power 106 in L.A. to promote VH1 "Hip Hop Squares," which premieres Wednesday night.

TMZ Sports broke the story -- Cube and his BIG3 partner, Jeff Kwatinetz, are suing a bunch of Qatari investors who were supposed to invest $5 mil in Cube's pro hoops league.

In fact, they recently added the CEO of Qatar Airways to the list of defendants.

Cube says the Qataris made up every excuse in the book to avoid ponying up -- and now him and Jeff are seeking $1.2 BILLION in damages.

Clearly, Cube's confident these billionaire dudes are gonna get schooled in the courtroom -- and he ain't afraid to let 'em know.

The BIG3 founder also told us why fans should be hyped for Season 2 -- and we would be too with all the big names comin' in.

2:46 PM PT -- The investment group named in the lawsuit, Sport Trinity, has issued a statement saying:

"The Sport Trinity investors have to date contributed more than 3.5x any other investor in the BIG3, putting in close to half of all funds invested in the BIG3 and multiples of what Ice Cube and Jeff Kwatinetz themselves invested."

A YouTube star who goes by the name ThatPoppy is accused of stealing the identity of fellow YouTuber Mars Argo, and Mars says her ex-bf, Titanic Sinclair, is behind the dastardly deed.

Mars claims in a new lawsuit she and Titanic were an item for 5 years, but that all changed after Titanic became violent and even suicidal in 2014 when she says they broke up.

During happier times, Mars and Titanic were prolific, producing 92 super popular videos featuring Mars singing.

But, love is a fleeting thing that often turns bad after breakups, and Mars says that's exactly what happened. She claims Titanic hitched his wagon to ThatPoppy, who starred in Comedy Central's "Internet Famous with Poppy."

Mars says Titanic and ThatPoppy completely mimic her songs. Even worse, she says ThatPoppy started looking creepily like her ... rabbit ears and all.

So Mars is now trying to sink Titanic, claiming copyright infringement, emotional distress and other stuff. She's also suing ThatPoppy for uncreatively pilfering her persona.

Mars' lawyer, Matthew Umhofer, tells TMZ, "Both Mr. Mixter [Titanic] and Poppy are frauds. Their only artistry is con artistry: Their only original creation is the suffering they've caused my client."

Jonathan Martin has received a judge's permission to leave a mental health treatment facility in the wake of his arrest for criminal threats ... but he'll be tracked by a GPS device.

TMZ Sports has obtained docs showing attorneys for the former Miami Dolphins lineman appeared in L.A. County Superior Court last week to ask the judge for his release from a facility in Malibu.

As we previously reported, Martin was arrested back in February after posting a threatening photo on social media featuring a gun and bullets. Martin had included a cryptic message aimed at former teammates and classmates.

When cops located Martin, they found several weapons including a loaded gun, a knife and an axe. He was immediately detained and transferred to a facility for mental evaluation.

The L.A. County D.A. later hit Martin with 5 charges ... 4 counts of making criminal threats and 1 count of possessing a loaded firearm.

Now, after the clinical director at the treatment facility vouched for Martin in court, the judge allowed him to be released with several conditions:

1) He must be fitted with a GPS and alcohol monitoring ankle bracelet

2) He must attend outpatient treatment 5 days a week from 9 AM to 5 PM

3) He's also been ordered to stay away from Harvard-Westlake high school in L.A. and the Miami Dolphins organization -- specifically, his former teammates Richie Incognito and Mike Pouncey.
