RIP

Post Malone got some new ink last week to honor his late friend, Lil Peep, and flaunted it -- in all its amazing detail -- as he left Poppy in WeHo.

We got Post Monday night and, as soon as we offered condolences ... he stopped to pay tribute. He flashed the new tattoo of Peep's face on his left arm.

Post also had some kind words about Peep's brief career and his impact on music.

As we first reported, Peep's apparent OD death is now the subject of a police investigation.

Lil Peep's death is now the subject of a police investigation and some very troubling private messages are under the microscope ... TMZ has learned.

We've learned the Tucson PD has opened an investigation into Peep's apparent OD from less than 2 weeks ago.

Law enforcement sources tell TMZ ... police are interested in texts allegedly sent from a woman named Mariah Bons ... who we're told went to the tour bus to see Peep shortly before he died.

She allegedly sent a message to a friend that reads, "GBC [Lil Peep] high af because of me and my friend lol."

Bons also allegedly texted, "He passed the f*** out my brother called and I tried to get him to say hi to my brother but he wouldn't wake up ..."

TMZ broke the story ... cops are also investigating whether the Xanax Peep ingested was laced with fentanyl.

Lil Peep's death investigation has cops now looking to see if the powerful opioid fentanyl played a role in the rapper's death ... TMZ has learned.

Law enforcement sources tell TMZ ... cops in Tucson are on the hunt after receiving multiple tips the New York rapper got his hands on some incredibly toxic drugs laced with the potent opioid.

You'll recall fentanyl also contributed to the accidental ODs of Prince and Eric Chase Bolling Jr.

Cops know fentanyl is a problem in Tucson and beyond. What makes it especially dangerous is that even a tiny dose can kill ... especially someone who is not a regular opioid user.

As we reported ... Lil Peep's body was found on the bus last week with drug paraphernalia, Xanax, loose marijuana and an unknown tan powder.

The Ohio State football team will honor former college superstar Terry Glenn with custom helmet decals when the Buckeyes face off against big-time rival Michigan this weekend.

Glenn -- who died in a car accident in Texas on Monday at age 43 -- was an All-American receiver for the Bucks ... and won the Biletnikoff Award (given to college football's best receiver) in 1995.

Terry Glenn, Jr. revealed the design on social media, saying "How awesome. Much love to all the Buckeyes out there."

Faith Evans says it's a sign of the times that an auction house is trying to make money by selling a pic of Tupac's junk.

We got Biggie's widow Wednesday at LAX and she expressed dismay about Tupac's selfie that's hitting the auction block. But as bad as that is ... she thinks auctioning off the door of the car in which Biggie was gunned down is even worse.

David Cassidy might be gone, but his old mansion in Florida is very much in business.

Cassidy's former waterfront home in Fort Lauderdale is currently for rent, with prices ranging from $1,200 to almost $2,000 a night depending on the season. Right now, it's going for around $1,500/night ... winter comfort ain't cheap, ya know?

Folks wanting to crash in Cassidy's old digs have to shell out for a minimum of 3 nights, but it might be worth it considering everything there.

The 6-bed, 6-bath estate is adjacent to a private lake with a dock. It also comes with a pool and spa, an outdoor barbecue, a volleyball court and complimentary paddle boards and kayaks for the adventurous types. There's a bunch of Cassidy memorabilia on display, too. Awards, personal posters, and videos of his concerts ... like a mini Cassidy museum.

Terry Glenn's son says Tom Brady's touching tribute to his father meant the world to him ... telling TMZ Sports he got chills when he read the quarterback's message about the late NFL star.

We spoke with Terry Glenn Jr. about the outpouring of kind words he's received since his dad's fatal car accident Monday morning ... and he says Brady's words were "more than special" knowing his first career TD pass went to Glenn.

The 21-year-old says he'll always remember how his dad vowed to give him a better childhood than he had ... and how hard he worked to make sure he was taken care of.

As for Glenn's 83 Kids Foundation for foster children ... Terry Jr. revealed he was actually scheduled to travel to Texas to help work with his dad on Monday ... but says he's still committed to continuing his charitable cause.

Terry Jr. also shares his favorite memory growing up with his dad ... and it's an amazing story.

David Cassidy, the 'Partridge Family' heartthrob who sold millions of records and became the fantasy of millions of girls, is dead.

Cassidy died in a Florida hospital after his organs failed.

Family sources tell TMZ, David had been on life support since Monday. Doctors advised the family Tuesday the only way David could survive was with a liver transplant, but he was not a candidate because he would never survive surgery. The family decided at around noon to remove life support.

A number of family members were present when David died, including his brothers Shaun, Patrick and Ryan, his children Beau and Katie, along with various nephews and his ex-wife, Sue Cassidy.

We're told death came almost immediately after life support was withdrawn.

TMZ broke the story, David was in need of a kidney transplant but ultimately doctors said it was futile. His liver and other organs shut down and early Sunday his son and ex-wife were summoned to the hospital to say goodbye.

Cassidy was a multi-faceted entertainer ... from singing, to acting to Broadway to Vegas. "The Partridge Family" hit like an earthquake and catapulted him to stardom. The show ran from 1970 - 1974 and produced hits like "I Think I Love You," "Come On Get Happy," and "Doesn't Somebody Want to Be Wanted."

David reluctantly auditioned for the role of the guitar-playing Keith Partridge and producers cast him not even knowing if he could carry a tune.

After "The Partridge Family" ran its course, David recorded a number of solo hits, including the remakes of "Cherish," "How Can I Be Sure" and "Rock Me Baby."

He took the starring role on Broadway in "Joseph and the Amazing Technicolor Dreamcoat" from 1983 to 1984.

David was the son of actor Jack Cassidy and Broadway performer Evelyn Ward.

David guest starred in a number of TV series, including "The F.B.I." "Marcus Welby, M.D.," "Ironside," "Bonanza" and "Medical Center."

Cassidy battled alcoholism for most of his adult life.

He's survived by son Beau, daughter Katie -- who stars in "Arrow" -- half-brothers Shaun, Patrick and Ryan, step-mother and co-star Shirley Jones and ex-wife Sue Shifrin-Cassidy.

Charles Manson made several phone calls to a documentary film crew in the final year of his life ... which they're now releasing to the public.

TMZ got this exclusive look at the REELZ project called "Charles Manson: The Final Words."

We're told the doc -- which has been in production for about a year -- was initially scheduled to come out in 2018, but the network decided to bump that up, because as they say ... strike while the iron is hot.

It features phone convos with Manson from Corcoran State Prison -- the most recent one in July. Rob Zombie narrates the documentary, which presents a new theory behind why the murders happened.

It also provides a look at Manson's cult through his eyes ... in the months leading up to his death. 'Final Words' airs December 3 at 9 PM ET on REELZ.

Eddie George says he'll always remember Terry Glenn as a "good kid with a big heart" ... telling TMZ Sports he was honored to call the late NFL receiver his teammate.

George and Glenn played together at Ohio State in the '90s and later in the NFL with the Dallas Cowboys. The Heisman trophy winner says he admired how well Glenn thrived despite losing his mother at 13 years old.

"He was a great guy to be around. Great person," George says ... "Just always full of laughter and joy despite his troubles."

"He overcame a lot of that stuff and didn't succumb to the pressures around him and really made something positive out of his life."

George goes on to share his favorite memories of playing with Glenn ... and says he'll do whatever he can to help his family.

Roy Halladay was flying dangerously close to homes -- and making wild turns and adjustments in altitude -- moments before his fatal crash ... this according to the NTSB.

The National Transportation Safety Board released the preliminary report regarding the Nov. 7 crash in Florida that killed the former MLB pitcher.

GPS data obtained from the plane shows Halladay was climbing and diving around the crash site -- and at one point, flew "as close as 75 feet to the Gulf Harbor South Beach houses."

The report also references video of Halladay's plane taken before the crash which shows the aircraft flying around 10 feet above the water. Unclear if the report is referencing the video obtained by TMZ Sports, but the description is very similar.

One witness also told the NTSB that he saw the plane perform a 300 to 500 foot climb before heading "a 45 degree nose-down attitude."

The witness says he then saw the plane crash into the water and "nose over."

The plane was recovered for inspection -- and investigators say the parachute was NOT deployed.

The report says Roy had only taken delivery of the plane on Oct. 10 ... just 28 days before the crash.

Halladay was 40.

Ron Goldman's father is demanding O.J. Simpson get before a judge ASAP ... because he's concerned Simpson is pocketing cash he owes to the Goldman and Brown families.

In docs obtained by TMZ ... Fred Goldman says the first available hearing date isn't until July 3, 2018 ... which he says is way too far away. He believes in that 7-month span O.J. "could flood the market with sports memorabilia" and try to keep all the money for himself.

O.J. responded in his own docs, saying the secret autograph session he held in October was a one-off ... and he's just trying to "readjust to civilian life." O.J. says even though he's had a lot of money-making offers ... he's rejected all of them except for that one autograph sesh.

11:36 AM PST -- Roman Polanski's attorney, Harland Braun, tells TMZ ... "The murder of Polanski's wife and unborn son still remains too painful for him to make a statement. He hopes someday to correct the legal proceedings in L.A. so that he can visit their graves at Holy Cross Cemetery."

Roman Polanski -- who was married to Sharon Tate when the Manson Family slaughtered her and their unborn child -- remained deeply involved in the Manson case right up until Manson's death.

Debra Tate tells us, as soon as she got word from the prison that Manson was dead, she contacted the famed director. She says he's been closely following the machinations of the Manson case, especially the various parole hearings.

Debra also surprisingly says Manson is the lesser of the evils in the notorious Family.

Beloved singer and actress Della Reese, best known for starring in "Touched By an Angel," died Sunday night ... according to her family.

Della had battled diabetes for years. Her family says she passed away in her California home.

She co-starred with Roma Downey on 'Angel' ... playing Tess. She had big movie roles too, like "Harlem Nights" and "A Thin Line Between Love and Hate" -- and was the first black woman to guest host "The Tonight Show."

Della was also an accomplished gospel singer -- Mahalia Jackson discovered her. She went on to become an ordained minister in the 1980s.

Della was 86.

Charles Manson's body is sitting in Corcoran State Prison, where it will be for the next 10 days ... and if no one claims it he'll be cremated.

TMZ broke the story ... Manson died in a Bakersfield hospital and the body was immediately taken back to the prison.

Our sources say Manson did not designate a person to take possession of his body. Under California law, if the body is unclaimed for 10 days the prison will have him cremated. The prison has the option to bury Manson, but we're told cremation will be Manson's fate.

The state will also take possession of any property Manson left behind, and any funds he left will be used to cover cremation costs.

Lil Peep took a nap before his Tucson show and never woke up ... according to the police report.

Peep's manager says she saw the rapper early Wednesday on his tour bus and he appeared to be fine. She says Peep took a nap around 5:45 PM and when she checked on him a short time later he was snoring and breathing without issue. After being unable to wake him, she decided to let him sleep longer.

The report says when Peep's other manager checked on him later in the night, the rapper was completely unresponsive and his team began CPR.

Cops say when they arrived, they discovered several Xanax pills, loose marijuana and an unknown tan powder on the rapper's tour bus.

Lil Peep was just 21.
