Hook Ups

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.

Lil Wayne's finally making it official ... the rumors about him banging Christina Milian are 100% true! Why else would they be holding hands in public?

But we suggest they take it slow. Wayne has some potent sperm -- as his FOUR baby mamas can tell you.

Billy Ray Cyrus has NO PROBLEM with his daughter's boyfriend getting chummy with chicks in Cabo.

Miley's dad was out in L.A., when a photog asked about Patrick's now famous Spring break, and Billy Ray made it clear ... he's team Patrick all the way.

The other way to interpret the video -- and accurately we might add -- is that Billy Ray's stamp of approval is proof Miley has forgiven her BF and all is well.

The Game puts work before pleasure ... 'cause even though the rapper is hanging with one of Justin Bieber's former hookups -- it ain't funny business, just money biz.

Sources close to model Chantel Jeffries say The Game definitely wants her ass ... as the star of his upcoming music video shoot. We're told that's what they were discussing while they grabbed a bite at The Ivy Tuesday afternoon.

Besides, they're both kinda spoken for -- Game with his ex-fiancée, Tiffney Cambridge ... and Jeffries with The Weeknd.

Still, we know Game's hip to the paparazzi game -- so he damn well knew lunch at The Ivy would start a buzz ... about him and Chantel, and his video.

It's called showbiz for a reason.

One of Wilt Chamberlain's former teammates is calling out the NBA legend -- telling TMZ Sports there's NO WAY he took down 20,000 women ... because he was too busy taking down McDonalds.

We spoke with Tom Hawkins -- who played 2 seasons with Wilt on the Lakers back in the '60s -- and he's adamant that Wilt "The Stilt" must have inflated his numbers in his tell-all book.

"I played with him for 2 years ... I doubt his numbers are correct."

And why is Tommy (who played 10 solid years in the NBA) so steadfast in his belief?

"Because too many nights I saw him going back to the hotel with nothing but a bag of McDonalds."

Rock legend Jimmy Page has a whole lotta love ... for a girl 46 years younger than him!

The iconic 71-year-old Led Zeppelin guitar god was spotted walking hand in hand in London with Scarlett Sabet, a 25-year-old actress.

Creepy fact: Page has a 44-year-old daughter. She's a photographer ... named Scarlet.

Lil Wayne did it big in Hollywood ... as in big PDA with Christina Milian -- the first public confirmation of the rumors they're banging.

Weezy and Christina were leaving a movie set on Tuesday and he had a firm grip on her hand ... something we've never seen them do out in the open. In fact, other than an appearance at an award show, the couple's been kinda like a unicorn.

Christina -- who's signed to Young Money -- has been mum about dating the boss, but this is clearly their coming out.

As for why Wayne was holding her hand so tightly -- just a guess, but Drake was spotted in town.

"Empire" stars Andre Lyon and Anika Calhoun are family on-screen ... but off-screen the actors may be hooking up.

Check out this video of Trai Byers, who plays Andre, and Grace Gealey, the now-famous Boo Boo Kitty. They went to a wedding together and people who went to the reception tell us they were super affectionate at times, but still conscious people were looking.

The bride and groom -- Lauren Whitney Johnson and Cedric Sanders -- are both actors, but nowhere near as famous as Lucious' oldest son and ex-fiancée.

Kylie Jenner might only be 17, but her trash talking game is fully grown ... after she not-so-subtly taunted her mortal enemy Blac Chyna.

It started Tuesday night when Blac Chyna posted a photo showing off her sick Audemars Piguet watch. It's pretty clear Tyga gave her the watch back in the day (2013) when they flaunted their matching bling.

A few hours after Blac Chyna posted her timepiece, Kylie posted a pic of her wearing the exact same watch, with the caption "Currently."

Kylie first posted a photo of the watch back in December.

Tyga's got to get more creative with his girlfriends. Then again, cat fights are pretty awesome.

Patrick Schwarzenegger looked the worse for wear in Malibu Saturday.

Arnold's son returned from Spring Break in Cabo, where he got chummy with a couple of chicks, apparently much to the dismay of Miley Cyrus.

One girl was his best friend's girlfriend, and the other was his ex, but it was all out in the open and certainly looked innocent enough ... to some, but not MIley.

Patrick and a few buds hit up a Malibu restaurant, where he hooded up, looking pretty pensive.

Patrick is a student at USC. Miley didn't go to college. Is this just part of a ritual that Miley doesn't understand, or does she have a point?

Pop singer Becky G is hooked up with Austin Mahone -- or at least that's the buzz -- so we put her loyalty to the test with the ultimate tweener who'd ya rather: Austin or Justin Bieber?

18-year-old Becky was leaving The Troubadour when our photog threw out the question -- cleverly trying to get her to confirm she's truly the #1 Mahomie ... but instead of taking the bait, she surprised us by choosing door number 3.

You might recall, Justin and Austin once had beef over Selena Gomez -- but rest easy ... there won't be a repeat battle with Becky. Check out who's topping her charts.

"Shark Tank" star Robert Herjavec has an interesting way of saying goodbye to his "friends" ... by planting a big, juicy wet one on their smackers.

Robert and his "Dancing with the Stars" partner Kym Johnson were leaving Greenblatt's Deli in Hollywood Friday night, where they were full-on kissing.

A coy Robert explains, they're not dating ... they're just friends who dance.

They've actually been very open about their relationship ... people on DWTS all know the deal.

Jamie Foxx was more than happy to stop for photogs Friday so he could shoot down stories that he's dating Katie Holmes.

Foxx was at an ATM in Westlake when he was asked about the reported relationship, and he joked that the tabloids have been trying to make that a story for 3 years.

Jamie said -- and we've independently confirmed -- he was around Katie quite a bit recently for an animation project they are doing with "CSI" creator Anthony Zuiker.

Patrick Schwarzenegger's just doing what every guy does on spring break, but in these new photos he happens to be doing it with his ex-girlfriend ... which will be harder to explain to Miley Cyrus.

The pics just surfaced from the same day he was doing body shots off his BFF's girlfriend ... and relatively speaking, they're pretty innocent.

PS and the green bikini hottie -- named Taylor Burns -- are chatting, laughing, and she was even considerate enough to rub suntan lotion on his back. The sun IS hot down Mexico way.

Here's the thing ... guys and girls socialize on Spring break -- sometimes up close and drunkenly. Patrick's just having a regular college experience. His challenge is Miley didn't have that experience.

Still, we gotta say the ex-factor does complicate things. Good luck, Patrick.
