Dating

Calvin Harris is putting on a good face ... even if he's hurting inside.

The superstar DJ stepped out Thursday in L.A. and said he's aces with Taylor Swift's new relationship with Tom Hiddleston. Check out the vid ... Calvin tries to play it cool as the ex.

On the surface he's putting on a happy face ... but as TMZ reported he's actually PISSED it went down and dirty.

A month before splitting with Calvin, Taylor Swift had eyes for Tom Hiddleston ... or so it seems.

Check out this pic, taken May 1st, at the end of a pre-Met Gala dinner at Anna Wintour's house. Tay seems to be peering in the direction of an unsuspecting Tom, who's jawboning with Idris Elba.

Tom did a radio interview not too long ago (above) where he strongly suggests Taylor made the first move ... at the May 2nd Met Gala.

As we reported, we're told Calvin believes his ex and Tom were together weeks before they called it quits on June 1st.

Calvin Harris suspected something was up with Taylor Swift weeks before their breakup ... and his suspicions were confirmed Wednesday when pics surfaced of Taylor making out with Tom Hiddleston ... this according to sources connected to the former couple.

Our sources say Taylor and Calvin were in a "committed relationship," but he suspected something was up in early May ... a month before their breakup.

As we reported, at the time of the breakup Calvin posted there was still "a huge amount of love and respect." Hours after the photos surfaced Wednesday, Calvin deleted the tweet.

We're told, "He's pissed and feels betrayed by her."

Taylor and Tom were out May 2, dancing at the Met Gala ... Calvin and Taylor announced their breakup June 2.

Calvin was mum Thursday. As for Taylor and Tom ... another song in the making.

Taylor Swift's already moved on  ... to actor Tom Hiddleston, just two weeks after her breakup with Calvin Harris.

TMZ has confirmed Taylor and Tom have formed a dating union. Truth be told ... it wasn't hard to confirm, after photos surfaced of the two passionately kissing.

The 35-year-old Hiddleston played Loki in 'Thor' and there's a buzz he's the new James Bond.

Taylor and Tom were dancing together at the Met Gala back on May 2 when she was still with Calvin.

Tayhid?

Miley Cyrus is a serious triple threat ... just check out the merch.

Miley was all smiles with Liam Hemsworth Tuesday night in NYC. It's easy to see why she's got a wide grin ... she's got her man, a HUGE rock and dough pouring out of her purse.

Get it, Miley.

Leonardo DiCaprio looks pretty smitten by Nina Agdal, which makes total sense. She's a smoke show SI swimsuit model, after all.

The actor was all smiles hanging out with Nina over the weekend at The Crow's Nest in Montauk, NY. Our witnesses tell us they smoked for a few hours in the lounge area waiting for a table ... before finally heading in for dinner.

Once inside, they sat on the same side of the table and Leo had his arm around her. We're told Nina even got a little something from the gift shop -- a poncho ... cause it was raining.

If ya got all wet, might as well be with Leo ... said a looooooooong list of hot chicks.

President Obama got in the way of potential true love when the people protecting him opened a can of whoop ass on an unsuspecting NYC bicyclist.

Daniel Provencio tells us he was hot to trot for a blind date -- pumping "Call Me Maybe" through his headphones -- when NYC cops tackled him for riding into a secured area just before the Prez breezed through.

Turns out Daniel was on his way to hook up with a guy he met on an online dating website the night before ... he wouldn't say which.

Daniel was coy about date specifics, but suffice to say the other guy lost interest because Daniel was hours late after being interrogated by authorities.

Daniel called the guy when he was released, but, as he puts it, "Manhattan men are huge on punctuality."

Urijah Faber says he won't be doing any horizontal wrestling with Paige VanZant outside the Octagon ... 'cause the almighty BRO CODE would stop him from ever, ever, dating his super cute UFC teammate.

We got Faber out in L.A. doing a little press for UFC 199 .... and asked about the smokin' hot ... and apparently single ... Miss VanZant.

Basically, we wanted to know if there was any chance he'd make a run for the 'DWTS' runner-up ... and become the first couple of the UFC.

Urijah makes it clear ... it's NOT HAPPENING ... saying the fact Paige dated his (and her) teammate, makes any extracurricular grappling a clear violation of the almighty bro code.

Bonus awesomeness? Faber also talks to us about his signature butt chin ... and tells us who he thinks has the most iconic booty face in the history of Hollywood.

Kylie Jenner and PartyNextDoor added a touch of romance to Drake's Memorial Day party by getting up on each other on the dance floor.

It's the first time we've seen video of the new couple showing some PDA. Normally, they go out of their way to NOT look like they're together.

Justin Bieber's back in the dating game with an on-screen hottie ... or so it seems.

The Biebs and actress Nicola Peltz -- she starred on "Bates Motel" and 'Transformers' -- arrived for a dinner date at Mastro's Steakhouse in Bev Hills Wednesday night. She looked casual in black, while Justin looked parched ... in a severe sunburn.

He's a freak for some sun.

Kylie Jenner took about a minute to get back in the game, because she was out Wednesday night with her rumored new BF PartyNextDoor.

Kylie and PND were leaving the TCL Theatre where they hit up Russell Simmon's All Def Comedy Live.

Tyga who?

Before he was trying to bang chicks on a tropical island, one of the bachelors on the new FOX dating show "Coupled" was a college football WR ... who played with DeSean Jackson and Marvin Jones.

Alex Lageman even bragged about days on the Cal Berkeley football team -- where he played mostly as a backup from 2007 to 2010.

When one of the ladies on the island asked about Alex's hand size, he busted out this gem -- "I played receiver in college, so they're big enough to catch balls."

Nice.

Kylie and Tyga are finished ... dunzo ... for good-zo.

Sources connected to the former couple tell TMZ ... it happened days before the Met Ball last week. They were both at the gala, but they did not walk the red carpet together, and that was her decision.

As for why ... everyone's being tight-lipped, but we do know this. Tyga took his mom and a model to Mother's Day lunch ... and he's not telling his friends whether she's his new GF.

We also know this ... the breakup was acrimonious. We're told Kylie was bent out of shape that Tyga had the nerve to go to the Met Ball. He was only invited because of her, and she's mad at herself that she didn't think to have him made persona non grata.

The 2 have broken up before, but we're told this time there's no going back.

Tia Shipman didn't exactly spill the beans when we asked about her new pro athlete BF, but she slipped us enough hints to help us crack the case! We think.

The actress just joined the "WAGS" cast, and when we saw her out in West Hollywood we tried our best to get the name of the baller she's banging. Check out the vid ... Tia refused to give up the surprise, but played along with our game of 20ish questions.

We walked away thinking it's the Washington Redskins new cornerback Greg Toler.

Fresh off her divorce settlement, Kaley Cuoco's cozying up to her new boyfriend, and while it's plenty clear he has NO interest in her fortune ... he's more than happy to be her bag man!

Kaley and Karl Cook did dinner Monday in NYC, and as they stepped out of their ride her arms were full with a coat, while Karl toted what looked like her purse. Classic move --- for an old married couple, but these 2 have only been dating for a few months.

As we first reported, Kaley held on to all of her $72 million 'Big Bang Theory' money in the divorce from tennis pro Ryan Sweeting ... thanks to an ironclad prenup.

Toni Braxton put some respek on Birdman's name by hanging with the Cash Money CEO -- and it's not for the first time ... which makes it more surprising they've kept this under wraps.

The cat started crawling out of the bag when Birdman showed up Sunday for Toni's Grammy Park performance in Brooklyn. We're told backstage was sealed off so very few people could see them together, but this pic of the rendezvous got out.

Sources tell TMZ ... Birdman left with his entourage to go clubbing. It's unclear if he and Toni had a "run-in" later, but we're told they've been close for years ... and have hooked up in the past.
