Hook Ups

Patrick Schwarzenegger and Miley Cyrus put that whole "Patrick flirts on Spring Break" thing completely behind them, and went out Thursday afternoon for brunch.

Patrick and Miley are regulars at the popular Studio City joint Hugo's (order the Papa's Eggs, thank us later) and according to an eye witness ... Miley ordered up their famous Green Juice.

You'll recall they also hooked up for sushi last week -- so, it's 100% smooth sailing again.

Our spy says they came together (Patrick drove), stayed about 45 minutes and Patrick was in full-on boyfriend mode, opening doors and the like.

Getting out of the dog house takes work.

Cody Simpson is a robot ... or he's the biggest friggin' Knicks fan in the world, because not even a stone cold 10 like Gigi Hadid could break his steely gaze from the game.

Cody lived every dude's dream Wednesday night at Madison Square Garden ... courtside seats and a supermodel pawing at you like you're her first meal in weeks. Yet, all the Aussie singer cared about was watching the hapless Knicks lose to the Nets.

Amber Rose and James Harden have decided to put their bangship on hold ... mutually deciding to enter the desolate and barren void known as the FRIEND ZONE ... TMZ Sports has learned.

James and Amber had been rumored to be seeing each other ... with Amber attending a Rockets game in Houston and reportedly gushing to friends about how sweet Harden was.

Rose even publicly proclaimed on "The Breakfast Club" that she might let the NBA's leading scorer sink a bucket on Valentine's day, if he "acted right."

But we've learned the two are officially DUNZO romantically ... and that it was the the distance between them that turned their Sonny & Cher into a Murtaugh and Riggs.

Bottom line -- start lining up fellas ... seems like this is back on the market.

Michael Strahan has hooked up again ... and showed off his pretty chick in St. Barts.

The athlete/commentator/talk show host/rich person was ready to flaunt his relationship while vacationing with 2 other couples -- including fellow ex-NFLer Tony Gonzalez and his wife.

It seems the stories that surfaced months ago he and Nicole Murphy might get back together ... are ancient history.

As for the lucky chick -- we're told she's not just a vacay hookup. She and Michael have been dating for a few months.

Michael -- who's co-starring in "Magic Mike XXL" -- may have retired from football, but no one told his body.

Hmmmm ...

Don't know what to say about this. Brett Ratner making out with a chick on the same yacht where he was nuzzling Mariah Carey.

People on the boat said Brett and Mariah were in full-on couple mode, and we're told both of them loved our posts over the weekend.

But check this out ... Brett on the same yacht Sunday night in the Caribbean, sucking face with another chick.

Kylie Jenner may have had the last word in her watch-off with Blac Chyna, but Ms. Chyna is letting her arm do the talking.

You'll recall ... the 2 girls played the game, "Tyga loves me more" last week when Blac Chyna posted a pic of an expensive watch Tyga had given her back in the day, and then Kylie posted her watch -- almost identical to Blac Chyna's -- with the word, "Currently."

Mariah Carey celebrated the birthday of her boyfriend, King Brett Ratner Saturday ... aboard the USS Rich People.

TMZ broke the story ...Mariah and Brett are in full-blown couple mode, sailing around the Bahamas on a mega-yacht owned by one of Brett's billionaire friends.

It's interesting ... these 2 have been friends for a number of years and worked together on Mariah's music videos as well. But it's clearly turned into a lot more.

French Montana may have violated the laws of the Sea-Doo Saturday ... because it sure looks like he's drinking on the watercraft.

French was traversing the area around Diddy's house, drinking from a Ciroc vodka bottle and looking like a spokesmodel. The photog who shot the pics says the Sea-Doo is owned by Diddy, who BTW also owns Ciroc.

Of course it's possible he's doing something promotional for the vodka and it's actually water, but that would seem like the worst promotion ever -- drinking while boating.

He's steering with one hand as he takes swigs.

And check this out. Khloe just posted a photo on top of Diddy's roof, showing them partying with French -- vodka in hand -- with the caption, "The Ciroc made us do it!!#stepIntoTheCircle."

Mariah Carey and Brett Ratner have pulled a Swift/Harris ... they are full-throttle together.

This pic was taken Saturday on a yacht in St. Barts. Sources -- let's just say close to the boat -- say they're all over each other. She's totally into him and he is nuts for her.

Ratner recently said he and Mariah were just really good friends, calling rumors of romance "ridiculous." Well now that's just ridiculous, because they're in full romance mode. We're told she's over Nick and moved on.

Ratner has directed a bunch of films, including "Rush Hour" and "X Men: The Last Stand." He also directed music videos, including Mariah's "Obsessed," and "Touch My Body."

It's very age appropriate -- they're exactly one year apart. Her birthday was Saturday and his Friday.

Justin Bieber has just learned what most men realize at his age ... hickeys are for kids.

Truth be told, we don't know for sure it's a hickey, but let us deconstruct. JB was poolside Friday, and strategically covered up his neck with a towel.

He was there with Kendall Jenner and Kourtney's kids. Others may have been there as well.

When he went to Mastro's Friday night, he lost the towel and the marks were apparent.

Calvin Harris went from outright rejecting Taylor Swift to embracing her, and several friends tell us, there's a business side to his change of heart.

Calvin and Taylor are now full-on dating, but just months ago he said he would left swipe her on Tinder because she's "the opposite of my type."

So why the change of heart? Our sources who are prominent in the DJ world say Calvin got to know Taylor through the Haim sisters, Taylor's best friends. Calvin and Haim have a hit song, "Pray to God," that was released earlier this month. He got to know her and liked her.

But our sources say Calvin is the best businessman among DJs and knows the cache of dating the biggest pop star in the world.

They believe Calvin has developed feelings for Taylor, but they say he's wired for success and there's no hard dividing line separating his personal life from business.

Taylor Swift wanted to make one thing clear at Kenny Chesney's concert in Nashville ... she's banging Calvin Harris.

The video we got of them holding hands as they left the concert is but one example of strategic PDA. People who were around them said Taylor was sitting on his lap for a long time. There's also a pic of Calvin with his arms wrapped around Taylor's tiny waist. And an eyewitness says they kissed.

Taylor left Calvin's side for a while to dance in the aisle and then she went onstage to perform a song with Kenny.

On Wednesday, Swift and Harris were spotted around town doing a little food shopping and Taylor hit up one of Harris' shows in Las Vegas earlier this month.

This is stunning ... Calvin Harris went way beyond saying he was not into Taylor Swift ... he said she's the OPPOSITE of his type.

Calvin went on "Capital Breakfast," a British radio show, in November and was asked about Tinder and the celebs who would earn a right swipe.

You gotta hear him ... he's not putting us on. Calvin says Taylor earns a solid left.

Jennifer Lopez and Casper Smart did NOT get back together, because we found out they were never really apart.

Sources close to the couple tell us ... the break-up they announced in June was a business move. Multiple sources say in the spring they did stop seeing each other, but only for a few weeks.

We're told JLo was hawking her movie, "Boy Next Door," and honchos on the film felt creating a buzz that she was hooking up with co-star Ryan Guzman would help sell tickets. It's hard to do that when you're not single.

But the decision wasn't one-sided. We're told Casper was up to the same thing because he was shooting "Street," a UFC fighter movie where he buffed up. Again, he was more appealing single.

It all makes sense now. Two months after they revealed their break-up, a photog got shots of them in a convertible BMW. When JLo saw the photog, Casper put the top up and she slumped down in the passenger seat, out of sight.

Then in December, a dog at Jennifer's house bit a neighbor. Turns out it was Casper's dog that did the deed and he came running out of the house in his pajama bottoms after the attack.

In February, Casper went to a GQ event, and when he left he walked down the block and jumped in a car JLo was driving, avoiding photogs. A few minutes later a photog saw them walk into a restaurant together. When they saw the guy they hightailed it inside.

And then they got bolder, dancing together at a Big Sean concert at the House of Blues in WeHo.

Case closed.

Taylor Swift and Calvin Harris surfaced in Nashville ... could it be?

Taylor and the famous DJ were coming out of Whole Foods Wednesday night -- wearing matching shirts no less -- when 2 people snapped the pics.

This isn't the first time they've been together recently. Taylor went to Calvin's concert in Vegas earlier this month. There were reports he chartered a jet to fly her to the gig.

They got all flirty at the Brit Awards after-party in London back in February.

Shopping for food together ... hmmm.

Not that Jennifer Lopez and Casper Smart have been fooling anyone -- but they're officially banging again ... and we're basing that on the fact they're finally swapping spit in public again.

Smart swung by "American Idol" Wednesday night to scoop up JLo and they kissed out in the open for everyone to see. They've been sprinkling clues for months -- slipping out of a GQ event together, partying at Big Sean's House of Blues gig ... and his dogs were at her house (which didn't end well).

They broke up last April after 2 1/2 years, but what if it was all for show?

J.Lo's insisted they're just friends, but after so much smoke ... this has to be a 3-alarmer.
