Breakups

Kylie and Tyga could not co-exist because their relationship became an unrelenting test of who was more important ... at least that's the way Tyga sees it.

Sources connected with Tyga tell us, he was battling Kylie almost daily over who should kowtow to who when there was a scheduling conflict. They were fighting over which events they'd attend together, which required one of them to scrap their plans.

Tyga is telling friends the Kardashians fueled the conflict because Kylie would complain about him and the family would stoke the coals by telling her that her career was far more important than his.

Tyga's people say this did not come to a head Thursday ... it's been brewing for weeks.

Morena Baccarin is about to drop major coin on her soon-to-be ex-husband Austin Chick ... a judge just ordered her to pay him almost $23k a month.

Here's the breakdown ... Chick gets $2,693 in child support, and a whopping $20,249 for spousal support. It adds up to more than $275k a year ... so Chick won't exactly have to wait tables.

As we previously reported, Baccarin and Chick have joint custody of their 2-year-old son Julius, but since she films in NYC, he mostly stays with his mom.

Kylie Jenner and Tyga have broken up, and it was sudden and nasty ... TMZ has learned.

Sources connected with the couple tell us they split Thursday, just after Kylie returned from Australia. One source says, "It's something Tyga did," but the source would not be specific.

Sources connected with Tyga say Kylie's the one who pulled the plug and it had something to do with "pressure from the Kardashians."

Kendall was out Thursday night at dinner and we're told she was upset and had harsh words about Tyga.

Kate Beckinsale's husband has been hitting the town like a very single guy over the last month ... a single guy out with a very young model.

42-year-old Len Wiseman has been spotted out -- sans wedding ring -- with 24-year-old CJ Franco. They were out Tuesday night at The Nice Guy, partied until 2 AM and left together.

It's the third time we've seen Len out with CJ, as 42-year-old Kate is ensconced in Prague shooting "Underworld 5."

Kate and Len married in 2004, but it sure seems the marriage has come to a screeching halt.

We reached out to Kate's people but mum's the word.

Nicki Minaj is about to get sued by her ex-boyfriend Safaree Samuels, and he's gunning for a fortune.

Sources connected with Safaree tell us he wants a cut from 3 of Nicki's hugely successful albums -- The Pink Print, Pink Friday and Pink Friday: Roman Reloaded.

Safaree also wants a piece of the pie from some of Nicki's biggest singles, including "Only" featuring Chris Brown, Drake and Lil Wayne, "Flawless (Remix)" with Beyonce and "Feeling Myself" with Bey.

We're told Safaree will present a boatload of proof he was super involved in Nicki's work. His evidence includes videos of him working with Nicki, voice memos from recording sessions, hours of footage from studio sessions. He says he also has multiple witnesses to validate his contribution.

And Safaree says Nicki herself acknowledged his contribution by giving him executive producer credit on her first 2 albums.

Our sources say Safaree has already lawyered up and a lawsuit is "imminent."

Giada De Laurentiis moves fast ... and she's got fast moves.

The cooking star and her new BF Shane Farley were all over each other in Houston Saturday night at La Grange bar.

Giada -- whose divorce became final in September -- was all over Shane, and he was more than a willing participant.

Giada was in town for a book signing earlier in the day ... lipstick in tack.

Scott Disick and Kourtney Kardashian were spotted together Friday night for the first time publicly since their breakup in July.

The two were in Malibu celebrating the release of celeb pastor Rich Wilkerson Jr's new book. In a video from the party, you can see them standing together ... and Scott looks totally tame.

They weren't the only big names at the event ... Justin Bieber, Patrick Schwarzenegger and Omarion also joined in.

As TMZ reported -- Kourtney has left the door open for Scott -- and we're told he's a completely new person now. Looks like they're starting off on the right foot.

Scott Disick is a changed man thanks to rehab, and the Kardashians are loving it ... so much so, Kourtney has NOT completely closed the door on a reconciliation.

We're told Scott spent time with his kids and some of the Kardashians Wednesday night, and seemed like "a whole new him." Our source says he's been "amazing" since checking into rehab last month, and he gets a day off here and there to see his kids.

And get this, Kourtney might still be open to patching things up. We're told it would take a LONG time for Scott to prove himself again, but it's not officially over.

Shortly before he met up with the fam, Disick was looking healthy and refreshed around Malibu.

Wiz Khalifa and Amber Rose threw the "L" word around a lot when they reunited on the Sunset Strip ... and it sure looked like someone was catching feelings again.

The exes chopped it up outside 1 OAK after French Montana's birthday party, and anyone standing nearby might have thought the old spark was coming back. Especially when Amber started banging on Wiz's window, screaming about a chick in the SUV with him.

But the drama ended with a laugh, and while both talked to us about their "love" ... they also squashed any "getting back together" rumors. Amber was passionate about someone else -- a chick who yelled, "What a slut!"

Amber's response is awesome.

At least one of Derek Jeter's many MANY famous ex-girlfriends is thrilled for him now that he's engaged to Hannah Davis ... telling TMZ Sports, "He's living his dream."

We spoke with model Vida Guerra -- who dated Jeter way before Jessica Biel and Jessica Alba -- who tells us she's genuinely happy #2 found his #1.

"He said once he retired he wanted to get married .... so he's living his dream. Congratulations to him."

Question is ... is Vida jealous that Hannah got the rock and not her???

We asked. She answered. Check out the clip.

Oh, and also check out Vida's hot modeling pics to see what Derek's missing out on. Damn.

Miranda Lambert's 32nd birthday is all rainbows and unicorns -- well, she's got the hard part of that done, anyway.

Miranda's pals helped her shake off a rough year -- y'know divorce and such -- and showed up at her home in Nashville to slap a horn and some paint on her horse named Sophie.

Not sure if Sophie appreciated it, but at least it looks like Miranda's having a good day.

Iron Chef Cat Cora's marriage to wife Jennifer Cora has disintegrated and all signs point to a bitter custody struggle over their 4 kids.

TMZ has obtained the dueling divorce docs ... both women filed on the same day, with Jennifer requesting full physical custody of their kids. Cat is asking for joint physical custody.

The two have been married since 2013 and have four sons together -- 3 of whom Jennifer gave birth to and 1 who was carried by Cat.

Cat's been the breadwinner, which is probably why Jennifer's asking for spousal support.

Cat's had her share of problems, most notably getting busted for DUI in June 2012.

Cat's been a food force for a long time ... she's one of the original American Iron Chefs, and she operates 4 restaurants.

Cat was most recently a guest judge on "Cutthroat Kitchen."

Karrueche Tran is the prototype of post-rapper breakup success ... which is why Rick Ross' ex Lira Galore has reached out to Tran's camp for an instruction manual.

Sources close to Lira tell us she met with Karrueche's manager, Jacob York, this week in Atlanta to see if he could provide career guidance. Lira -- whose engagement with Ross ended last week -- was impressed with how Karrueche remained relevant after her breakup with Chris Brown.

Lira's got plenty of modeling under her belt, but what she really wants to do is act. Karrueche has made the transition, acting in "The Bay" and "Vanity."

Here's a free tip ... keep your body hot and ass cheeks exposed. Take it from Karrueche.

It was a nice little run, but Gigi Hadid and Joe Jonas are done -- they're breaking up.

TMZ confirmed the couple formerly known as G.I. Joe decided to call it quits after what amounts to an extended summer fling. A source close to the couple tells us it was all about their schedules. Joe wanted to focus on his new group DNCE ... which is just kicking off a new tour.

And of course, Gigi is busy being one of the hottest models in the world.

They were last seen out on Oct. 25 in West Hollywood (not looking thrilled), and the fact they weren't together for Halloween, and Gigi was solo at Kendall Jenner's party ... shows the split's been in the works.

It's particularly bad timing for Joe, since he could've had a front row seat when Gigi walks the "Victoria's Secret Fashion Show" next week.

Rick Ross and Lira Galore have called off their engagement, less than 2 months after making the leap.

We're told they had a major blowout, although it's unclear what it was about -- but it was serious enough that Lira moved her stuff out of Rozay's Georgia mansion.

Ross spontaneously popped the question back in mid-September while they were jewelry shopping in New York. They'd only been dating a few months at that point.

As for the giant 11 carat, $350k rock he gave Lira ... so far there's been no discussion on whether she'll return it. She still had it on her ring finger in a photo she posted a day ago.

The good news for Rick -- legally speaking, the ring is a gift in contemplation of marriage. Translation: Lira gotta give it back.

Though she might want to reconcile ... after talking to a lawyer.

9:20 AM PT -- Miles addressed the alleged assault on his Instagram Monday morning saying, "Woke up this morning to more gossip, slander and lies ... I've never put my hands on anyone ..."

"Love & Hip Hop: Hollywood" star Miles Brock was arrested Halloween night after allegedly attacking ex-BF Milan Christopher who's also on the show.

Law enforcement tells us Milan went to NYPD cops Friday night, claiming he and Miles ended up at the same party, they started arguing and Miles slugged him in the face.

Milan filed a police report and the next night Milan tracked Miles down in Times Square, found a cop and pointed Miles out. The cop cuffed Miles and placed him under arrest for assault.
