Hook Ups

Ariana Grande has a big problem with boyfriends screaming from the mountaintops that she has a priceless p***y ... which is why she says she called it quits with Big Sean.

Sources connected with Ariana tell us ... the last straw was when Sean dropped his track, "Stay Down," in which he raps:

I ain't even gonna lie, I got a million dollar chick
With a billion dollar p****y
Every time I c*m, I swear to God I feel like I be rich

We're told Ariana felt humiliated because Sean was treating her like a piece of meat. Ariana's grandmother came to her and asked about the lyrics, which was especially embarrassing.

But there was plenty of tension leading up to the song. Sean claims she made him pay for all sorts of extravagances. But our Ariana sources say SHE is the one who foot most of the bills, including vacations and private flights.

As we reported, Sean complained that Ariana didn't show up for his big House of Blues performance in February because she selfishly cared more about her Grammy's performance the following day.

But our Ariana sources say it was Sean who was self-absorbed. Ariana's Grammy performance was live and during the day on Saturday when she rehearsed her voice was strained and her vocal coach ordered her not to even speak for the rest of the day, and Sean got pissed.

As for Sean saying Ariana set up the Bieber stage grab to humiliate her, Ariana says it's total B.S. ... they were already broken up and she did NOT ask Bieber to engage in a stunt. And she says Sean never even brought it up.

We expected Tyga to go on a profanity-laced tirade after his ex, Blac Chyna put his texts to her on Instagram for the world to see -- but instead he's taking a low-key approach ... at least for now.

Blac Chyna posting the texts was her going nuclear in her war with Kylie Jenner -- but Tyga is clearly a casualty too. In the messages, Tyga (who is apparently "Kings Father" in BC's phone) begs, "Can I just come for a lil. Just us 3. Do something or spend a lil time."

The direct shot at Kylie comes when he allegedly tells BC he wants "to be a family again" -- and adds, "Want to start this friendship. Relationship."

Tyga responded early Friday morning, writing, "Focus on what's real in life. And surround yourself with people that you really care about.its simple."

Not sure how long cooler heads will prevail in this mess.

Sorry ladies, Rob Gronkowski is officially taken ... dating a super hot former New England Patriots cheerleader ... multiple sources close to Gronk confirm to TMZ Sports.

The object of Gronk's affection is Camille Kostek -- who was on the cheerleading squad in 2013 and 2014 ... before switching careers and becoming a TV reporter.

There have been multiple sightings of the couple out and about recently -- but now, our Gronk sources say it's official ... they're dating and they're not trying to hide anything.

Congrats!!

Ariana Grande lashed out at Big Sean almost immediately after their breakup by staging Justin Bieber's come-from-behind stage embrace ... so claim sources close to the couple.

Sources closely connected with them tell TMZ ... Sean claims it was him who broke off the relationship because she was "immature."

Sources say the downfall of their relationship started in February, when he made the most important appearance of his career at the House of Blues in West Hollywood. Everyone showed -- Kanye, Bieber, JLo, Chris Brown, Jay Z, A$AP Rocky, Tyga, Kylie and Kendall -- everyone EXCEPT ARIANA. We're told she needed to get ready for the Grammy's the next day, which he found extremely selfish.

Sean also traveled to see her "10 times more" than she went to see him. He claimed once she demanded that he blow tens of thousands of dollars to take a private jet to see her. Sean, who grew up poor, felt she was a spendthrift ... a sign of immaturity.

But the crowning blow was just after the breakup. They were still talking and the door was slightly open for a reconciliation, when Bieber jumped onstage in L.A. and grabbed Ariana from behind. Even though Ariana pushed Biebs away, Sean believes it was all calculated -- NOT by Bieber but Ariana -- to hurt him.

Matt Bellamy finally put the moves on his Kate Hudson doppelganger, because he and the gorgeous "Blurred Lines" music video star Elle Evans are now definitely banging.

Sources close to the new couple tell us Bellamy and Evans officially became an item back in March and were practically inseparable at Coachella, doing what all new couples do ... making out and taking sappy photo booth pics.

We're told they were also handsy last week at the Burberry Fashion Show in L.A. -- but she hasn't met his son yet. As we previously reported, they first met back in February through mutual friends ... and things heated up shortly after that.

We ran into Elle Wednesday at The Ivy ... and she was super tight-lipped re: Matt -- although she kinda slipped up as she said goodbye.

Selena Gomez's trip south of the border is strictly professional, meaning she's not banging Hit-Boy.

Selena caused quite the stir in that ugly bikini earlier this week, but less prominent was the famed producer who was by her side. Stories started surfacing that they were dating.

Our Selena sources say not true. They're recording an album at the home of Joe Francis, Casa Aramara, in Punta Mita.

Turns out Kanye and Kim went to Joe's house last year and he build a sick recording studio on the compound. Hit-Boy -- who's produced hits for Kanye, Jay Z, Chris Brown, Snoop, Bieber and many others -- heard the studio was gold and that's why he chose it for Selena.

There are extra perks ... an awesome beach, and even a sea lion that swims in Joe's pool.

BTW -- black bathing suit MUCH hotter.

Rapper YC has been granted a stay of execution -- the ex-fiancee he cheated on the night before they were supposed to get married ... is willing to give him a second chance with one BIG condition.

YC's lady, Tia Anderson tells TMZ ... the wedding could be back on IF he can stop creeping behind her back -- particularly when he's about to walk down the aisle! We broke the story -- Tia called off their Las Vegas ceremony last month when she caught him messing with a bartender.

Tia says she and YC haven't seen each other since things blew up less than 3 weeks ago, but they are texting and talking -- and he even sent her roses. He's gonna have to do way more than that.

She says the biggest issue is YC laying off the rapper lifestyle -- meaning, stop surrounding himself with groupies and THOTs. YC claims he's down to do what's necessary -- including couples counseling -- but Tia's still deciding whether she can trust him again.

Translation: His punk ass needs to suffer for a while.

Tip for YC: Record something romantic, instead of songs like "Racks." Also ... stop hooking up with random chicks.

The epic bachelor bash Ray J threw for "Hollywood Hillbillies" star Paul "Tha Pimp" Conolon was so big and beautiful ... it apparently got him banned from Paul's future in-laws' home.

We're told Ray J and David Weintraub were in the hot seat with fiancee Dee Dee Peters' family after they threw a dicey stag party for Paul, who's obsessed with big women. So to fulfill his wish, there were plenty of over-sized strippers at the venue, Pinz Bowling Alley in the San Fernando Valley.

Who said strippers don't come cheap? The whole thing cost $750.

The good news ... Dee Dee and Paul still got married.

We love happy endings.

Shelly Sterling says she didn't go after V. Stiviano for the money -- SHE WANTED JUSTICE -- and says she plans to give away every single cent she won in her crushing court victory to a charity.

Our sources say ... Shelly was "out for blood" from the start -- and really wanted to put the screws to Stiviano for all the crap she put her family through.

In fact, Shelly told the Associated Press ... her lawsuit was about getting even with Stiviano who had "harmed" her in so many ways.

Of course, Sterling won a $2.6 million judgment against Stiviano -- ordering her to fork over the keys to her $1.8 million condo AND $800,000 in cash.

Sterling says she doesn't even want the money -- 'cause she's a billionaire -- and to prove it, she's giving every cent to a worthy charity.

“Wolf of Wall Street” hottie Margot Robbie's BF grabbed two giant scoops of her smoking hot ass on the streets of Toronto -- the kinda PDA that makes ya think ... these kids will never break up, right?

Well, that depends on whether Margot chooses true love, true career advancement -- or door #3 ... the Gronk(owski) option!

"Wolf of Wall Street" star Margot Robbie's boyfriend has his hands full ... of that ass.

Looks like Robbie and aspiring director BF Tom Ackerley want everyone to know they're not only in deep, but they're also not afraid to put the PDA on full throttle .. the two went at it Monday on the streets of Toronto.

No doubt she'll be slipping into something tight for her role as the Joker's squeeze, Harley Quinn, in the upcoming DC Comic bad boy blockbuster, "Suicide Squad" ... which she's up there filming.

Drake was not grossed out when Madonna planted a prolonged lip-lock on him at Coachella Sunday night ... his reaction was all about lipstick aftertaste.

Sources close to Drake tell TMZ ... he loved the kiss. As for whether the kiss was prearranged, Drake says it wasn't ... the plan was for Madonna to dance around him while he sat in the chair.

Drake says he was not banking on a transfer of the glossy stuff and that's why he blanched.

When you look closely at the video, it looks like whatever lipstick there is it's pretty colorless ... either nude or beige.

Drake fulfilled every young man's fantasy (in 1985) of making out with Madonna, but it's 2015 and he looked disgusted by the whole thing.

Madge made a guest appearance Sunday night at Coachella during Drake's set. She did a few songs and then went in for the prolonged kiss ... as Drizzy just sat there.

Check it out ... it sure looks staged. In fact, Madonna recently said one of her dreams in life was going on a date with Drake and kissing him. That said, he sure looks disgusted afterward.

Rapper YC -- aka Yung Chris -- just learned fidelity is a key part of marriage ... especially the night before your wedding.

YC and his GF of 5 years, Tia Anderson ... decided to elope at the end of March, and invited a handful of family and friends to join them at the Bellagio in Vegas. What they didn't plan on was the smokin' hot bartender.

YC's rep Kali Bowyer says Tia spotted YC -- best known for his hit, "Racks" -- getting handsy with a hotel bartender on Friday night ... and immediately pulled the plug on the Saturday ceremony.

YC's telling friends nothing happened with the drink-slinger, but admits it was heading in that direction. Not that it matters to Tia ... the damage was done.

As for the ring -- we're told Tia's keeping it. If YC's looking for ice ... try the bartender.

Bradley Cooper got pretty cozy with ex-GF Suki Waterhouse Saturday at Coachella, and by the looks of it old habits die hard.

Bradley and Suki were together for 2 years, until they split last month. But it seems they were feeling the music.

Bradley also met up with Clint Eastwood, the director of his movie, "American Sniper" ... chowing down on pizza.

Justin Bieber and Kendall Jenner play by different rules than most of us -- or they're just straight up banging ... because 'just friends' don't take pics like this.

Biebs certainly loves his puppies because he spent a romantic day out near Coachella with three of his current favorites ... he posted the disgustingly cute photos with Kendall and Esther.

Check out JB's hand -- friends don't go for the waist touch and neck sniff just for fun. In other words ... if this isn't for a magazine cover -- pretty sure they're screwing.
