Dating

Turns out, there's a good reason Scott Disick's been partying in Miami the past couple days ... he pissed off the Kardashians.

Sources close to Scott tell us ... he secretly flew a girl to Costa Rica -- where the Kardashians were filming their show -- and put her up at a hotel where the crew was staying. It's pretty clear ... the Kardashians didn't want an interloper while they filmed, so Scott tried to keep it on the QT.

We're told someone from the crew ratted Scott out, telling Kris and Kim about Scott's muse. Our sources say Kim and Kris had a ferocious argument with Scott. It had nothing to do with Kourtney ... that relationship has been over for a long time. They felt it was disruptive and disrespectful.

Scott didn't see it their way and bolted to Miami. It's unclear what happened to the girl, but days later he was with another chick ... and the next day still another.

Scott, we're told, is more than happy hanging in Miami ... way happier than shooting the show.

Scott Disick has a revolving door policy when it comes to models hanging poolside ... but one thing they're all down to do is show off their asses.

Scott cozied up to a blonde Tuesday at the Setai Hotel, the day after he was chilling in exact same spot with a different woman.

We broke the story ... Scott's fling with model J Lynne was temporary -- as in 24 hours. With his one-and-done policy in place ... expect to see a new face butt next to him tomorrow.

Scott Disick got a better vacay offer than hanging with Kourtney and the rest of the Kardashians -- and we got some awesome shots of said better offer.

Scott popped up in Miami on Monday with a very young looking hot chick ... on the beach and in the pool at the Setai Hotel. She's cheeky, for sure.

Just a couple days ago, Scott was chilling in Costa Rica with Kourtney and their kids. He even proudly posted a pic.

But obviously, there's only so long Disick can hang in that situation -- before returning to his natural habitat.

The Lord is back ... on the prowl.

Big step for J.J. Watt ... the NFL superstar FINALLY went public with his relationship with his pro soccer star girlfriend -- by posting a couply picture on Instagram!

Obviously, this is a big deal.

Watt and pro soccer star Kealia Ohai have been dating for months -- but kept things extremely under wraps. No public outings. No Man Crush Monday or Woman Crush Wednesday posts. Nothing.

Until Tuesday ... when Watt posted a photo of the two during a recent beach outing and wished Ohai a happy birthday.

"Happy Birthday beautiful. May this be your best year yet! @kealiamae."

Watt has 2.5 million followers ... so, it's kind of like their coming out party.

By the way, Kealia also happens to be the sister-in-law of his Texans teammate, Brian Cushing -- so you can probably understand why Watt was being extra careful about how he handled the whole situation.

Selena Gomez and The Weeknd will be attached at the hip through Grammy weekend -- even though one of them is feeling way more wanted than the other.

The Weeknd has already officially made Selena his plus 1 for Clive Davis' huge annual bash on the eve of the Grammys. Sources connected to the couple tell us Abel's people contacted the party planners within the last few days ... a good sign he and Selena are getting closer during that Italian vacay.

Both are attending the Grammys, but as of now they're not sitting together. We're told Weeknd's putting in a request with The Recording Academy to change that ASAP.

But here's the thing -- Weeknd, a 2 time Grammy winner, is performing during the ceremony. He's one of headliner acts, and all over promos for the event. Selena, on the other hand, isn't performing -- nor was she nominated -- despite her #1 hit, "Hands to Myself."

At least she knows her bf wants her.

Selena Gomez and The Weeknd are trying their best to not look like international superstars while touring Italy -- but they're failing miserably.

The new couple's sporting hoodies, shades, overcoats -- attempting to avoid cameras -- while cruising around Venice by foot and boat. This tour comes a couple days after they took in a couple museums in Florence.

Selena Gomez dating the The Weeknd is even a big deal over in Italy.

The couple popped up Friday in Florence where they took in the local art at the famed Uffizi Gallery Museum. We're told there were about 20 people waiting to get in who were pushed aside so Selena and her beau could get out. There was at least one bodyguard with them.

Seems like things are getting serious, our source says they even kissed in public ... as they were boarding an employee elevator to make their exit.

It's interesting ... Selena's BFF, Taylor Swift, jetted off to Italy with Tom Hiddleston when they first started dating, and we know how that ended.

French Montana's not fazed at all by Iggy Azalea dating a new dude ... because he's the one who ended their relationship.

Sources close to French tell us he wants Iggy to be happy, and has no issue with her hooking up with music producer Ljay Currie -- who posted a pic wearing jewelry French bought for Iggy. We're told it's no skin off French's back ... he doesn't care what she does with the diamonds.

As for the rapper's tweet about shooting someone's "punk Asss," which seemed to be a threat aimed at Ljay -- it had nothing to do with him.

We're told French was in the studio that day laying down a new track ... and the "threat" was a lyric.

Selena Gomez and The Weeknd are clearly past the one-night stand phase, 'cause they're hanging out in public again ... this time doing it at a Dave & Buster's.

Selena and Abel hit up a D&B in Hollywood Wednesday night with a bunch of mutual friends -- including French Montana and Jaden Smith -- where we're guessing they ate, drank, and played.

This is the first time the two stars have been seen together since their makeout sesh at Giorgio Baldi a few weeks ago ... following all the drama that ensued.

And besides, if there's one thing anyone who's anyone knows about this place ... it's a total date night spot. Keyword ... date.

Kendall Jenner is definitely with A$AP Rocky ... at least for this week in Paris.

The long-rumored couple is there for a Fashion Week event -- newly single Bella Hadid was third wheeling it. Kendall was back in Paris for the first time since the Victoria's Secret Fashion Show, and this trip was arguably hotter.

Rocky and Kendall were all over each other at the club and on the way back to their hotel. If it's just friendship ... they're really good friends. They also kicked it in Malibu last month ... and more recently at a concert in NYC.

Friends. All around the world.

Iggy Azalea has moved on from French Montana.

The new guy's name is Ljay Currie and he's a music producer. The two got super touchy Sunday on a boat anchored off the coast of Cabo San Lucas.

Startin' to look like things are serious between Lakers guard Jordan Clarkson and model Hailey Baldwin -- the two hit up one of the hottest restaurants in L.A. together Thursday night .. in a Lambo.

The point is ... everyone in town knows Catch is a place you go to be seen -- especially when you pull up in a whip that costs more than most homes.

So, this could have been the official, "We're Going Public" night.

Clarkson and Baldwin have been spending a lot of time together lately -- and were spotted holding hands on New Year's Eve.

You looking for love, like Donald Trump, and long walks on the beach? Well, now there's a dating site for you.

TrumpSingles.com is up and running for DT supporters looking for like-minded souls to form a perfect union.

The site has 20,000 members and it's growing fast.

The dude who started it -- David Goss -- fired up the site last summer and offered to "make dating great again" at a cost of $5 a month. That price has now swelled to $19.95 a month.

Justin Bieber can spot an opportunist from a mile away ... at least now he can, and the opportunist is Selena Gomez.

Our Bieber sources tell us ... the singer says he's been there, and believes Selena's using The Weeknd for promotion. Bieber's intel -- and ours -- is that Selena and The Weeknd are working on music together.

We're told Justin feels this is all cookie-cutter stuff ... she did it with him, Nick Jonas, Zedd and now with good ol' Abel. When Selena wants to push new music, it seems she dates stars with whom she wants to collab.

Long story short ... we're told Justin's rolling his eyes at the Selena/Weeknd love story. Can you tell?

Suki Waterhouse knows age ain't nothing but a number when you're with a hotshot like Diego Luna on his home turf.

Paps got the British model hanging out with the 'Rogue One' star in Tulum, Mexico over the weekend, and they looked pretty comfortable with each other ... especially Diego's right hand.

He's more than 10 years her senior -- Suki's just 25. But hey ... may the force be with 'em.

Bella Hadid believes Selena Gomez did her dirty by dating The Weeknd behind her back.

Sources close to Bella tell TMZ she feels betrayed because her ex and Selena hooked up almost immediately after Bella and Weeknd ended their relationship.

Here's where it gets interesting. We're told it was actually Bella who pulled the plug 2 months ago, because the bi-coastal relationship was just too difficult. Nevertheless, the breakup hurt.

Also interesting ... a Selena source says the thing between Selena and Bella's ex is 2 months old. They even spent the holidays together.

Bella is especially incensed because she and sister Gigi helped Selena when she was on the skids dealing with numerous emotional and other issues.

And there's more. Despite the 2-month relationship, Selena never uttered a peep about it to Gigi, who's her best friend. Gigi and Bella found out about it when they saw the pics on TMZ. And that's when Bella unfollowed Selena on Instagram.
