Hook Ups

Bella Hadid's rocking a ring on the traditional wedding ring finger ... but she and The Weeknd haven't gotten THAT traditional just yet.

When the couple rolled out of their London hotel Monday evening, photogs took notice of the golden piece Bella was sporting. Rumors immediately flew that Weeknd had popped the question, but hold your congratulations.

Bella's rep tells us there is NO engagement. They've only been together for about 10 months, so it would've been a pretty quick move on Weeknd's part.

Sometimes a ring is just a ring.

Katy Perry and Orlando Bloom had dinner with friends in Silver Lake Thursday night, but left alone in his car which means, if you couldn't tell by now -- they're totally banging! Maybe. Probably.

They've been inseparable since hitting it off at a Golden Globes party in January, even taking in last week's Adele concert together.

Rob Kardashian got a faceful of DNA on his way out of a laser skin treatment center ... courtesy of Blac Chyna.

BC gave her man a good ole fashion tongue bath outside the Epione Cosmetic Laser Center on Thursday evening -- a far more romantic display than the platonic one posted on IG a few hours earlier.

Now that we see the actual swapping of spit up close ... kinda sorry we questioned their passion. We get it guys ... you're really dating.

#ewww

Blac Chyna finally planted her lips on Rob Kardashian for everyone to see, but something might be missing here.

Considering Rob and Chyna have been almost inseparable for about a month now -- you'd probably expect something more passionate than a BFF-like peck on the cheek for their first Instagram kiss.

No doubt, BC's been great for Rob's confidence and his workout regimen, but c'mon -- where is the love? Where's the passion?

On the other hand ... this is the happiest we've seen Rob in years.

Leonardo DiCaprio keeps winning -- both for his role in "The Revenant" and with the leggy blonde contingent, because he had another one in his ear at a BAFTA after-party.

The latest Leo conquest -- Irish TV personality Laura Whitmore. They looked very cozy Sunday night in London, and while she is a hot chick and he is Leo ... sources close to Laura say it's not what people think.

We're told Laura was working, interviewing celebs at the award show -- and their convo was nothing more than casual, friendly cocktail party chatter. Leo would call that foreplay, but the source insists it was all "innocent."

Still ... Laura would fit right in with the rest of them.

Country music star Miranda Lambert is singing it loud and proud that she loves her R&B man Anderson East.

Lambert showed up to East's Valentine's Day show at Pearl Street Nightclub near UMass, and hit the stage alongside her man and sang Mariah Carey's "Always Be My Baby."

Best part of this video -- and their whole duet -- Miranda's gripping her beer through the whole thing.

Miranda and Anderson went public earlier this year, and it's easy to see why he's in to her.

Blake Griffin's nightmare 2016 continues ... 'cause now one of the biggest -- and hottest (seriously, watch the video) -- models in the world Samantha Hoopes has decided Griffin is no longer bangable.

Hoopes was out enjoying the night life at Super Bowl 50 -- we reiterate, LOOKING SUPER HOT -- when we asked if the hook up offer she made to Blake a while back is still in good standing.

Samantha said she was all about the Clippers stud when we shot her last year ... but that was before he punched out a guy half his size.

Check out the clip -- Hoopes says not only is she off Blake ... she's done with athletes ENTIRELY (yet, she's at the Super Bowl), claiming there's a new segment of rich guys she has her eyes on.

Good news for Blake? Like us, he can still enjoy super hot pictures of Hoopes.

Bad news? He's got an injured right hand.

Amber Rose and Wiz Khalifa are back in each others arms and damn near each other's mouths -- call it a possible silver lining to their epic Twitter beef with Kanye West.

Amber showed up in NYC to support Wiz at his album release party. It looked and sounded like they were putting up a united front ... mostly for their kid. Wiz gave his "baby mama" a shout-out from the mic, and Amber posted a pic captioning it, "supporting Sebastian's dad."

Things went from PG to PG-13 in the back of their ride home from the party.

Joe Jonas debuted a new bleach blond hairdo Wednesday night in L.A. that bares an uncomfortable resemblance to Zayn Malik's.

Of course it's uncomfortable since Zayn happens to now be dating Joe's ex, Gigi Hadid. Sure, it could be coincidence. Could be a single white dyed blond male.

Who wore it better? We're talking to you, Gigi.

Louis Tomlinson is so sure newborn son Freddie Reign is his kid, he has no plans to prove it with a DNA test ... TMZ has learned.

Sources close to Louis and Briana Jungwirth tell us the 1D-er's always copped to the kid being his ever since finding out Briana was pregnant. They started dating about a year ago and we're told things were so serious initially, he had zero doubt Briana was faithful.

While any lawyer would tell Tomlinson to seal the deal with a paternity test ... we're told he's totally cool with passing.

Dear Kendall Jenner ...

Sick of sharing Justin Bieber with your sister?

Well, meet Chicago Bulls small forward Doug McDermott.

He's 6'8". He's rich. And he's down to hook up!

Check out this clip of Doug in Bev Hills -- raving about the Kardashian family ... and Kendall in particular.

In fact, the guy hit TMZ Sports with the task of "hooking it up" ... so, here ya go!!!

Rob Kardashian apparently likes his women wild, because he couldn't wait to show his affection for the freshly freed Blac Chyna.

Rob and Chyna FaceTimed each other after she bailed out of an Austin jail. TMZ broke the story, Chyna was arrested Friday for public intoxication at the Austin International Airport after allegedly getting incredibly drunk and belligerent, even calling a flight attendant a "nasty ass bitch."

Some of the Kardashian girls did an oblique "I told you so" to Rob ... Khloe tweeting, "Damn!! On a Friday kid!!!"

As we reported, Rob wants to do a reality show with Blac Chyna.

Khloe and Kourtney Kardashian were hit with about a million questions about Rob, Blac Chyna, her arrest and their relationship Friday night as they hit up a club.

Khloe's mouth was as tight as her braids, saying nothing about kicking Rob out of the house after walking in on him and Blac Chyna last week.

Rob Kardashian packed a suitcase and moved in with Blac Chyna ... at least temporarily ... TMZ has learned.

Rob, who was living at Khloe's house, has been at B.C.'s digs for 5 days and counting. As for how it happened ... we're told Rob made the first move by DM'ing Chyna 2 weeks ago.

We're told Rob genuinely likes Chyna and is not hooking up to upset his family ... but we're told it has definitely upset the Kardashian brood. Kylie has been at war with Tyga's baby mama for more than a year.

Rob is using Chyna's home fitness equipment to train, with a little inspirational help from her.

Rob and Chyna have known each other for a long time ... since she lived across the street from the Kardashians.

Our sources say the Kardashians are outraged at Rob's hookup. They believe Chyna is manipulating everything and that SHE is the one who first reached out. They also say she's behind Rob's sudden interest in Instagram postings. They believe Rob's horribly depressed and she's playing into his insecurities for her own gain.

Rob Kardashian and Blac Chyna's budding relationship might have its roots in a theme park trip way back in 2013.

Rob and BC were photographed chilling at Six Flags Magic Mountain for Kendall Jenner's 18th birthday. The rest of the Kardashian family and a bunch of friends were there too. For the record, Blac Chyna and Tyga were still together.

Rob Kardashian put on his best pair of Yeezys and hit the gym with his girl, Blac Chyna -- and then she showed us exactly how she got him to work out in the first place.

BC posted a clip ... first from the kitchen -- looks like breakfast -- and then from the gym. You can clearly hear a guy in the background the whole time.

Our first clue it's Rob -- the guy's wearing Yeezys, the official footwear of Kardashian-Jenners everywhere. Also, the bird's-eye view of Chyna's boobs while she's on the elliptical is a dead giveaway. For the record, she's not showing a bit ... yet.

Get it, Rob!
