4:00 PM PT -- In a totally baller move ... Jen's party is moving to a brand new private jet. The backup PJ just pulled up in front of the damaged one and their luggage is getting transferred.

The 12 women onboard have been sitting patiently waiting for their plan B to arrive, but they're gonna have to get off now to stroll to the new jet.

Jennifer Aniston's private jet bound for Mexico was forced to make an emergency landing in California ... TMZ has learned, and now she and her guests are holed up onboard.

The flight took off from LAX at 11 AM Friday heading for Cabo San Lucas, but lost a wheel or a tire during takeoff ... according to the FAA.

The jet -- which also has Courteney Cox and Molly Kimmel onboard -- made it all the way down to Mexican airspace, but the crew decided it wouldn't be safe to land in Cabo.

The flight was diverted back toward the airport in Ontario, CA ... about 60 miles east of Los Angeles. However, they still had a very full fuel tank ... which ain't ideal for emergency landings.

The plane circled for hours to burn off fuel before it was deemed safe to land ... and the captain put it down safely at 2:05 PM. Jen, Courteney, and 10 other passengers have not de-planed yet, which is why we're watching the live stream.

There's a buzz Brad Pitt is on the plane. Not to be a buzz kill, but our sources say it just ain't so. We're told all the passengers are women -- including Amanda Anka (Jason Bateman's wife) -- and it's a surprise trip for Jen's 50th birthday which they sprung on her today.  

It appears everyone aboard is safe, but clearly a harrowing couple of hours for Jennifer to wrap up her birthday week.

Beck's divorcing his actress wife, Marissa Ribisi, after nearly 15 years of marriage.

The singer filed the divorce petition Friday in Los Angeles. He and Marissa got married in April 2004 and they have 2 kids together -- a 14-year-old son named Cosimo, and an 11-year-old daughter named Tuesday.

Marissa's had roles in "Dazed and Confused," "Pleasantville" and several other movies. She's the twin sister of Giovanni Ribisi.

This was the first marriage for both Marissa and Beck. They got married in a small ceremony in Santa Barbara.

The production company behind a Drake documentary is suing Universal Music Group for ratting them out, and getting the project yanked from streaming platforms.

Symettrica Entertainment rips UMG in the lawsuit, saying the music co. fired off notices to remove all the Drake music and video clips the documentary entitled, "Drake: Re-writing the Rules." Obviously, that would create a major hole in a Drake documentary ... if it were devoid of his image and music.

According to docs, obtained by TMZ, Universal's power move "has nothing to do with purported 'copyright infringement,' and everything to do with placating its artist Drake by attempting to suppress any commentary or criticism of Drake." 

The unauthorized doc was released on Vevo in November, and then hit Netflix, iTunes and Amazon on January 16. Symettrica says it got UMG's notice the next day and, 2 days later, all the digital platforms caved ... saying they had no choice but to pull the documentary.

Symettrica insists its use of the Drake clips was fair use, and says it's lost a ton of money because UMG shut them down. 

Symettrica wants the court to declare their use of the Drizzy clips is kosher. It's also suing UMG for damages. Drake is NOT being sued.

The death of Anthony Myrie, a NY state prison inmate, has become a cause celebre -- with Cardi B and Meek Mill suggesting a cover-up -- which is forcing the prison to release new details about the mystery.

New York Department of Corrections spokesperson Thomas Mailey tells TMZ ... the death of Anthony Myrie on February 11 at the Greene Correctional Facility near Albany "appears to be consistent with sudden cardiac arrest."

Mailey says the prison typically doesn't provide facts about an ongoing investigation, but it's making an exception due to "the abundance of misinformation in circulation."

After news of Myrie's death came out ... Cardi and Meek both shared a message from Myrie's family, alleging prison guards may have been responsible for hurting him. They also accused prison officials of lying about where his body was being held to "buy time to cover this up."

According to Mailey ... Myrie was involved in a 3-on-1 fight with other inmates, but officers broke it up without using force. Mailey says Myrie was examined after the incident and the medical staff found no injuries.

However, Mailey says Myrie complained of chest pain shortly afterward while he was waiting to be interviewed by prison staff. When they took him back to the medical unit, he collapsed ... "unconscious and unresponsive."

He was given emergency medical services by the staff before being transferred to Albany Medical Center, where he was pronounced dead.

According to the prison's statement, preliminary autopsy results show he had no body trauma and "the cause of death appears to be consistent with sudden cardiac arrest."

Ex-"Deadliest Catch" star Jake Harris is sitting behind bars -- and has been for more than 3 weeks -- after he was arrested for felony DUI and drug possession ... TMZ has learned.

The incident went down back on January 23 in Skagit County, Washington where cops say the 33-year-old wouldn't identify himself to park rangers, who tried pulling him over. Harris took off with his RV, forcing state troopers to chase him down and force him to stop ... according to docs obtained by TMZ.

Cops say the trooper noticed signs of drug use once they pulled over Harris -- pinpoint pupils, bloodshot eyes and pale face. They also say he could not stand still ... shaking the entire time and talking fast. Meanwhile, a K-9 alerted cops to drugs in the RV.

Cops say they found a half ounce of heroin and other paraphernalia associated with the selling of drugs. Cops say they also found a shotgun Harris claims he bought from someone for $150 and a "ball" of heroin. Turns out it was stolen.

He was arrested and charged with 4 felonies -- DUI, possession of a controlled substance, maintaining a vehicle or premises for drug trafficking and possession of a stolen firearm. They also hit him driving on a suspended license.

Harris was skipper of the Cornelia Marie before leaving "Deadliest Catch" in 2012, and has struggled with drugs.

His bail's been set at $200k.

Justin Bieber's mom wants his fans to understand the challenges her son is facing ... after multiple reports about him battling depression came out.

We got Pattie Mallette Friday at LAX, and asked how her famous son's holding up. Pattie didn't confirm Justin's getting treatment for depression, as reported, but she did tell us she's proud of how he's holding up under immense pressure.

She went on to point out just about everything Justin does becomes public news, and gave him props for holding up under those conditions. 

As you know, Justin's recently opened up about some of his old vices, including sex and drugs. He also revealed he abstained from sex in order to get closer to God.

Pattie makes it clear, Justin gets a big thumbs-up from Mom on the way he's handling the pitfalls of fame ... and life, in general.

A bunch of Mark Wahlberg's old and seemingly forgotten stuff has been found in abandoned storage units, and now ... a lot of it's hitting the auction block.

"Storage Wars" star Rene Nezhoda tells TMZ ... his friend Kevin went to a storage facility in the San Fernando Valley a few weeks back and bought 3 small lockers for $3k, which turned out to contain the actor's gear from years ago.

We're told the units contained some personal items -- family photos, kids' handprints and a dog's ashes -- but fortunately, Kevin was able to track down Mark's management and return them as a good deed ... free of charge.

All the other stuff is up for grabs, though ... with Wahlberg's blessing. As you can see in the pics, it includes old trophies and awards, golf photos, mementos from his "Boogie Nights" days, and yes ... Marky Mark memorabilia. There's also some furniture.

As for why Wahlberg lost ownership of the lockers -- Rene suspects someone on Mark's team simply forgot to pay the rent, and after 3 months of not paying, the lockers can go up for sale.

Kevin swooped and it's looking like a solid move. The items go up for auction Saturday.

Offset spoiled Cardi B on Valentine's Day with lobster, steak, champagne and diamonds -- but he also spoiled her attempt to drop a deuce! Yep, love stinks.

The Migos rapper spared no expense Thursday night, showering Cardi with TONS of gifts and romantic gestures. Fresh outta the doghouse ... Offset set up a candlelit bathtub session, and had his wife dripping in diamonds -- practically from head to toe.

But, the highlight of the night was Offset busting into the bathroom while Cardi attempted to, ummm ... clear the decks. Offset made it clear ... there was more than love in the air at that moment.

Check out the vid, 'cause in the end ... everything ended up exactly as you'd think.

The rappers hit up a strip club for some more booty action. It's kinda their thing.
