The Kardashians

Kylie Jenner's just too successful, too young and too hot to be tied down to one man, and that's the main reason she and Tyga are done for good this time.

Sources connected with the former couple tell us KJ recently realized she wants to live the single life and soak up the spoils of being an 18-year-old multi-millionaire. That frequently means flying all over the world for appearances, and we're told that didn't sit well with Tyga ... who's focusing on his music.

As one source put it ... she wants to jet set, he wants to chill in a studio -- and they both knew it wouldn't work.

Also, we're told since their mini break last fall ... there's been constant drama over "dumb stuff" -- what to eat, what they say on social media, blah, blah.

As for the model at Mother's Day brunch with Tyga? We're told he admits having a couple models "hanging around," but no serious girlfriends -- and Kylie's confident there was no cheating before they split.

Blac Chyna's 28th birthday was sooo money -- she made some, Rob Kardashian spent some and a bunch of strippers got covered in some. Win-win-win.

Chyna and Rob celebrated at Miami's G5ive strip club ... where she was hosting and paying rent for the best chicks in the club.

The mom-to-be got a giant cake delivered to VIP along with STACKS of cash, which was generously distributed to the dancers -- aka Chyna making it rain like hell on 'em!

BTW -- before Rob and Blac went to the club, they hit up Katsuya at the SLS South Beach Hotel and loaded up on just about everything on the menu, including sushi, steak, lobster, and lamb chops.

Check out the video ... not just for the exotic dancing, but for the massive birthday bling BC was flashing at the end of the night.

Scott Disick did sushi Wednesday with Kim Kardashian ... but nothin's fishy, because she's still his kids' aunt.

Scott and Kim chose the sushi restaurant with the most paparazzi -- Katsuya in Hollywood, but they were both mum on the way out.

The Kardashians just did what no lineman could ever do ... they stopped Lawrence Taylor dead in his tracks.

Marlon Wayans didn't wait for a photog to finish his question before UNLOADING on Blac Chyna and Rob Kardashian.

We caught up with the comedian at LAX who roasted the parents-to-be, poking fun at Blac Chyna's baby bump and her ass. Check out the video ... Marlon had a bunch of Kardashian material ready, and gave us his greatest hits.

Khloe Kardashian's still got a lot of junk in her trunk despite a rigorous workout regime that has every other part of her body slimming down.

Khloe ran errands Monday in Bev Hills, hitting up the Meche hair salon -- but in boots and jeans like this ... NO one was paying attention to her hair.

Ass ... still that family's greatest export.

Blac Chyna is not cutting the Blac out of her life anytime soon, and the only reason she's legally locking down her Kardashian name is to block squatters.

Sources close to Chyna tell us she wanted to make sure nobody else could cash in on her married name -- so she filed the docs to secure "Angela Renee Kardashian."

We're told BC is proud of the brand she's built, but realizes "Mr. and Mrs. Kardashian" might get better biz offers in the future than Blac and Rob -- and she wanted to have her ducks in a row if that becomes necessary.

She's already thinking like her in-laws ... we're told Chyna's inspiration was Kim -- who trademarked Kim Kardashian West when she married Kanye.

Kim Kardashian brought out her cleavage 'A' game for one of her last nights in Cuba -- but she got upstaged by her own daughter's dance moves.

Kim and Kanye West and the rest of the krew packed in a ton of activities before jetting off the island -- touring a bird sanctuary, an art gallery ... and a private dinner party, complete with salsa dancing lessons.

Check out the pics -- North, Penelope and Mason made grandma Kris proud. There will be another generation of 'KUWTK' ... for better or worse.

Khloe Kardashian shot a bunch of photos and videos of Lamar Odom on life support -- but he signed off on them being used on "Keeping Up with the Kardashians" ... TMZ has learned.

Sources closely tied to production tell us Khloe took the images of Lamar in his hospital bed, so she could "share with him his progress when he got better."

We're told when Lamar got better, Khloe showed him the images ... and HE decided he wanted them on the show.

Lamar Odom's near-death experience was never supposed to be on "Keeping Up with the Kardashians" -- or so we were told.

Sunday night's show featured Lamar hooked up to various forms of life support last October, shortly after he OD'd on cocaine.

During the episode the family talks about how Lamar looked in a Nevada hospital bed. They showed Lamar these pics after he'd completed his recovery at Cedars-Sinai in L.A.

Blac Chyna plans on introducing more than one new Kardashian to the world ... she's already set the wheels in motion to become a Kardashian and profit off the new moniker.

Chyna filed legal docs laying claim to the name "Angela Renee Kardashian" ... cornering the market for entertainment services, television and movie appearances, living as a "social media celebrity," and party hosting.

Her birth name is Angela Renee White.

As we reported -- Chyna and Rob are already fielding 7-figure offers for their own reality TV show.

Finally, a Blac Kardashian.

Lamar Odom swore to Khloe Kardashian he would not drink or do drugs after he nearly died from an OD last year ... but repeatedly he did not and probably could not keep his word, most recently as today.

Lamar was at the Beverly Center Sunday afternoon. As his friend shopped for shoes, Lamar retreated to a bar inside the mall, and went for the Cognac. He schmoozed it up with a few women, dropped $60 cash and beat a hasty retreat.

TMZ Sports broke the story, on Easter Sunday Lamar hit up a bar hours before going to church with the Kardashians and ordered 3 Remy Martins. Khloe almost immediately threw in the towel.

Saint West is already getting a taste of the family biz -- chilling in Cuba for the Kardashian family vacation TV shoot ... and making his paparazzi debut!

It's the first time Kanye West and Kim Kardashian have taken the 5-month-old out in public ... and Kanye looks every bit the doting dad.

Big sis North already looks like a natural in front of the camera -- so we're guessing in another year or so Saint will be freestylin' verses.

Rob Kardashian and Blac Chyna are about to expand ... we've learned she's pregnant!

Sources close to both Chyna and Rob tell us Chyna's several months along -- and it's not one of those, "Oh crap, you're pregnant" situations. We're told they're both super excited.

The baby will be Rob's first and BC's second ... she's got 3-year-old King, whose dad, of course, is Tyga.

Congrats.

11:25 AM PST -- Rob and Chyna just confirmed the baby news on Instagram with a pregnant Chyna emoji. Tyga also sent his well wishes, writing "Congratulations" under Chyna's announcement ... Kylie "liked" the post too.

Kim and Kourtney Kardashian's rugrats are digging the Cuban life.

North West, Penelope and Mason Disick had some fun in the sun at an "amusement park" in Havana ... remember everything's very retro down there.

The family is shooting 'KUWTK' on the island, and while the kids have their goals ... the moms do too.

¡Viva el culo!

Kanye West has no issue with bodyguards talking to Kim Kardashian, and absolutely did NOT fire one for doing so.

Sources close to the Wests tell TMZ ... Steve Stanulis was hired by the guy in charge of their security to help out before the Met Gala. We're told it was very clear Stanulis would only be used for the day leading up to the event. That's it, just a temp deal ... we're told.

There were reports 'Ye axed Stanulis for talking to Kim, but we're told Yeezy never had a confrontation with him, and in fact ... everything "went very smoothly".

Our Kimye sources say Stanulis has worked with them before, but since people in their camp believe he perpetuated the firing story for some publicity ... he won't get that chance again.
