Gilbert Arenas is being sued by his longtime girlfriend Laura Govan -- the mother of his 4 kids -- who claims Gilbert kicked her out of their L.A. mansion and then sold off her $1 million engagement ring.

TMZ Sports has obtained court docs filed by Govan ... in which she claims her and Gilbert are in the middle of a NASTY split.

In the docs, the "Basketball Wives LA" star claims she started dating Gilbert in 2002 ... before he made nearly $200 million in NBA contract money.

The two never had a formal wedding, but Laura claims they "lived together as husband and wife" and Gilbert promised that she would "share equally" in all of his earnings from 2003 on ... as if they were legally married.

Govan says the relationship fell apart around the end of 2014 ... when Gilbert "notified [Laura] to vacate the premises" of their home.

To make matters worse, Laura says Gilbert then "forcefully took" the $1 million engagement ring he gave to her in 2008 and sold it without her permission.

Now, Laura says she wants her cut of the Arenas fortune -- which she says includes profits from a number of marijuana clinics which she says Gilbert owns.

Kim Kardashian's former BFF Blac Chyna did something shocking by standing up for KK in the family feud with Rob -- even though she's pissed Kim's little sis swooped and scooped her ex.

We got Blac Chyna outside Greystone Manor Sunday night, and asked how she felt about Rob Kardashian comparing his sister to "the bitch from Gone Girl." We fully expected her to pile on ... especially since she and Kim had a falling out when Kylie Jenner started dating Tyga.

You gotta see this clip ... because at first it seems like BC and Kim signed a peace treaty. But when we ask if they're friends again -- the temperature plummets 20 degrees.

Scott Disick's officially ditched rehab in Costa Rica ... so he can spend quality time at the local nightclubs.

Disick was spotted hanging near the bar in a club called Rouge on Saturday night. Sporting a black tee and ball cap ... Scott seemed like he was trying to keep a low profile -- but hanging with a big bodyguard in purple ain't exactly inconspicuous.

Witnesses tell us he also hit up a spot called Vertigo.

TMZ broke the story ... Scott bailed on the Costa Rican rehab program after less than a week. He's coming back to the states, and already has club gigs booked back here.

After we posted our story, Scott posted (and then deleted) a photo touting his upcoming appearance at 1OAK in Las Vegas.

Oh boy ... David Letterman snuck out of his island retirement home without his shoes again ... at least it looks that way.

Dave was down in St. Barts this past weekend mentally preparing to step down from the 'Late Show' when he took an early morning Caribbean jog ... sans shoes, only socks.

There's a ton of studies about the benefits of jogging barefoot ... and Dave's embracing all of them during his island time.

Dr. Drew believes Scott Disick is in far worse shape than anyone believes, because his choice of rehab is dangerous, generally used by heroin addicts, and he's destined to relapse.

The good doc was at LAX Sunday when our photog asked about Disick's decision to leave the Costa Rica rehab facility Monday, after only one week of treatment. Scott says he has pressing business in L.A., but Drew says it's a common rich-people's avoidance technique.

1:30PM PST: Rob has now followed the family back on Instagram, including Kim.

Rob Kardashian clearly hates his sister Kim, comparing her to Amy Dunne, the sociopath from "Gone Girl" who killed her ex-boyfriend.

Rob just posted this pic on his Instagram, and it's really shocking. He's been MIA for months, but he's now re-surfacing in a big way.

Rob also just un-followed his entire family from Instagram.

You'll recall Rob bailed on Kim's wedding in Italy just before the photo shoot, and it seemed at the time there was bad blood, but that blood is clearly boiling now.

Scott Disick has decided he's too busy to stay locked down in rehab ... we've learned he's bailing on the facility in Costa Rica.

Sources close to Scott tell TMZ ... Disick had actually booked a flight Saturday to LA but he didn't get on the plane. Scott entered a rehab facility in Costa Rica last Monday, where he was undergoing an intensive therapy involving the African psychedelic shrub Iboga.

Disick's people tell us he decided not to take that flight but will leave that facility Monday because he has too much business in LA to deal with. As for why he didn't get on the plane today, we're told he wanted to complete a full week of treatment before bailing. The normal length of treatment is three times that -- 21 days.

Jill Blackstone, the "Jerry Springer" and "Sally Jessy Raphael" producer who was arrested for allegedly killing her sister, engineered a suicide pact but got cold feet at the last minute ... that's the operating theory of law enforcement.

Our law enforcement sources tell us, they believe Blackstone and her sister Wendy -- who was deaf and partially blind -- made the suicide decision and Jill executed the plan by putting a lit BBQ in their closed garage, which was supposed to fill the air with deadly carbon monoxide gas.

TMZ broke the story, Jill called a friend who called 911, and when paramedics arrived they found Wendy dead and Jill with severe carbon monoxide poisoning. They believe Jill was trying to kill herself along with Wendy but had a change of heart at the very last moment.

And cops believe the 2 dogs that died were part of the plan ... they would all pass together.

As we reported, police arrested Jill for murder but the D.A. sent the case back to the LAPD for further investigation and Jill was released.

We're kinda tired of solving this mystery, so we'll leave it to you. Is Kim Kardashian that fickle that she'd change her hair color twice in the same month, or is wearing a wig?

This pic was taken Friday in Calabasas. It paints a dark picture of Kim K ... this, just weeks after she became blonde during Paris Fashion Week.

Check out this pic Kim posted with her photographer, Ellen von Unwerth. BTW, Ellen specializes in "erotic femininity."

Now that we think about it, screw the hair. What's Kim up to now?

"Love and Hip Hop" star Masika Tucker is up in lights on the Sunset Strip, and lots of people who see her now think she's a whore ... and that has has triggered a bitter lawsuit against her co-stars.

The whole brouhaha is over a couple of strip clubs. A guy named Sam Sharif owns Ace of Diamonds in Vegas and Metropolitan Nightclub in WeHo, which has an Ace of Diamonds night every Monday.

Sharif hired Masika to promote the WeHo AOD, and part of the promotion was a big, splashy billboard on the Strip. It didn't sit well with Masika's enemies, "Love and Hip Hop" stars Nikki and Marcelle Mudarris.

Nikki and Marcelle actually rent their WeHo building to AOD, so they were really pissed off when they saw Masika's billboard. When Sharif refused to take the billboard down, Nikki and Marcelle put another billboard up nearby, with Maskika's mugshot from 10 years ago with the word "T.H.O.T."

Sharif says that billboard has torpedoed his business because he was catering to high-end clients and now people thinks it's a sleazy club advertised by a whore. He also says people think he's a fraud and really doesn't own the club.

Money cures all, and Sharif is suing for a million bucks.

"Shark Tank" star Robert Herjavec has an interesting way of saying goodbye to his "friends" ... by planting a big, juicy wet one on their smackers.

Robert and his "Dancing with the Stars" partner Kym Johnson were leaving Greenblatt's Deli in Hollywood Friday night, where they were full-on kissing.

A coy Robert explains, they're not dating ... they're just friends who dance.

They've actually been very open about their relationship ... people on DWTS all know the deal.

Ray J is pitching a new cooking show starring a guy who knows how to handle a knife ... sometimes against his own customers.

The "Love & Hip Hop: Hollywood" star believes Amy's Baking Company's fiery owners Samy and Amy Bouzaglo can carry their own show, so he and reality producer David Weintraub are pitching the couple once featured on "Kitchen Nightmares" to production companies around town. Also in the meeting was RD Whittington of Scottsdale Sports Car Group to discuss TV show plans.

You may recall the video of Samy going after a drunk and belligerent customer with a knife back in September.

We're told Ray J recently popped in to Amy's for lunch, liked what he saw and sealed the deal.

The show will be ser-rated R.

"Love & Hip Hop: Atlanta" star Joseline Hernandez must not watch her own show -- which is the only explanation for her denying under oath she ever hit Althea Eaton.

Eaton is suing Hernandez over the insane reunion show brawl. During her deposition, Eaton's attorney asked Hernandez if she has any recollection of ever hitting Eaton. You gotta watch the video of the fight and then listen to her answers.

So who are you gonna believe ... her or your lyin' eyes?

Vernon Turner got offed during the epic season finale of "Empire" ... and Malik Yoba just told us how he got the news his character was going to be the one to go.

Malik came on "TMZ Live" and laid out the painful moment Lee Daniels informed him his services would not be needed for Season 2 -- and it's a real kick in the gut. Let's just say he was doing charity work AND promoting the very show ... that was about to dump him.

Matthew Perry was involved in an early morning high-stakes chase ... he was spotted at the Commerce Casino putting up major bucks while sipping 'Bucks.

Witnesses say "The Odd Couple" star showed up before 7 AM Thursday morning and blew through at least $10k on 3-card poker before pulling out another ten ... all while slurping down java.

Now before you get too worried about Perry's bank roll, keep in mind he's reportedly worth around $70 mil and can afford to drop a few fat stacks ... all before breakfast.

Who knows, maybe he's doing hands-on research for Oscar Madison ... but may we suggest the $5 blackjack?

"Empire" creator Danny Strong seems fascinated by the prospect of a mashup between his show and "Scandal."

Strong was out Wednesday night celebrating the season finale of his EPICALLY popular show when we asked about the possibility of the two biggest shows on social media colliding.
