Hook Ups

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!

Rob Kardashian just kicked a social media hornet nest by joking (we think) about knocking up Blac Chyna, while also taking a jab at his sisters ... in one brilliant meme.

Rob posted the pic of BC carrying a baby car seat and saying she's out to birth the "next generation of the Kardashian name!"

It's a hardcore troll of Kim, Kourtney, Khloe and Blac Chyna's nemesis, Kylie -- especially since we know Rob's friends and family aren't happy about his hook-up with Chyna.

Funny to us ... but not so much for the sisters, we're betting.

Rob Kardashian and Blac Chyna have been getting hot and heavy in more ways than one.

Sources close to the unexpected couple tell TMZ, Chyna has been a positive influence on Rob because she's helping him get back in shape.

But don't get it twisted ... we're told they're definitely more than just workout buddies -- the romantic relationship is fairly recent, and things are more playful than serious.

Right now ... at this exact moment in time ... Draya Michele and Orlando Scandrick are back together.

Despite the fact they flip-flop more than a Washington politician, the former 'Basketball Wives' star says she's reconciled with the father of her fetus ... and they're finally in a good place.

As we previously reported ... about a billion times ... Draya and the Dallas Cowboys star have dated for a while (and broken up), got engaged (and called it off) and conceived a child (and broke up after that).

But this weekend ... Draya says they have worked things out -- and this time, they're hoping it lasts forever.

Rob Kardashian is in a vulnerable place right now and Blac Chyna not only knows it, she's taking full advantage ... according to people in Rob's inner circle.

Sources tell us Rob's close friends and family members tell us he's dealing with so much right now -- his ongoing weight issues and his recent diabetes diagnosis -- and they think BC made her move now, because his guard is down.

We're told they think Chyna really only wants 2 things: publicity and to get back at Kylie Jenner for hooking up with BC's baby daddy, Tyga.

Our sources say Rob's peeps think the fact Chyna's BFF Amber Rose just started following Scott Disick on IG ... is more proof this is a full scale "thirsty" attack.

They're all for Rob "having some fun" -- but they just hope he sees BC for what she is.

Blac Chyna and Rob Kardashian are banging ... or at least, spending enough time together that they should be.

BC posted a photo early Monday morning with some guy's heavily tattooed arm around her and she captioned it, "The beginning." We ran a quick tatt investigation, and the arm in the pic matches Rob's.

Sources close to both of them tell us ... Rob and Chyna have been together almost non-stop for several days. She used to live next to Kris Jenner's house, but we're told they never hung out back then -- so this is an all new hook up.

Since Rob's not much on going out in public, we see a lot of Netflix and chill in their future.

The Kylie Jenner look-alike who was spotted with Tyga this week has been in the picture for a couple months now ... TMZ has learned.

Her name is Val Mercado -- she's a 23-year-old model and aspiring singer -- and our Tyga sources tell us she's been very tight with him since shortly after his mini breakup from Kylie.

We're told they even hung out in Paris back in December when Tyga was there for a gig.

As for whether it's romantic -- we're told Tyga's interested in her ... for her music, and that's what he's told Kylie.

Although we haven't seen Kylie and Tyga together in a long time -- we're told they are still together, but as we reported ... they're focusing on their individual careers.

Don't hear this often -- Leonardo DiCaprio did NOT have sex with Rihanna ... despite the fact photos make it seem otherwise.

Leo and Rihanna did run into each other in L'Arc Nightclub in Paris early Sunday morning, and photos circulating of the meeting make it seem like they did some tongue wrestling -- but our well placed sources say nothing that hot happened.

We're told RiRi was hanging with Cara Delevingne, and when they saw Leo there was a friendly greeting ... including a kiss on the cheek which was captured by a photog. You haven't seen the pics because the agency hawking them claims Leo's people are trying to block the sale ... based on French privacy laws that protect public figures.

As for the make out rumors -- our sources say it's just a bad angle in the photo.

Of course, Leo and Rihanna hooked up about a year ago -- but we're told they're just friends now and Leo is definitely "single."

Miley Cyrus and Liam Hemsworth's renewed relationship is moving QUICKLY, as in ... they've already moved in together.

Miley and some friends drove a U-Haul truck over to Liam's pad in Malibu, where she unloaded junk from her trunk this weekend. It was the finale of her week-long moving process ... according to our Miley sources.

As we reported ... she's already wearing the engagement ring again, which Liam gave her years ago.

The 3 women Justin Bieber has either banged or is currently banging clearly have no hard feelings toward one and other, because they all partied together Monday night.

Kendall Jenner, Hailey Baldwin and Kourtney Kardashian kicked it at The Nice Guy in WeHo for about an hour ... arriving together no less.

It's clear Hailey currently holds the title, but no hard feelings from the others.

Scott Disick is no longer hiding his new relationship, because we got pics of Scott and girlfriend Lina Sandberg very openly showing affection in a very public place.

Scott, Lina and one of Scott's pals lunched at the Polo Lounge in Bev Hills. They were kissing inside the restaurant, located inside the very popular Beverly Hills Hotel.

Lina's a Wilhelmina L.A. model who knew him for awhile, but a month ago they went to Nobu restaurant in West Hollywood and the relationship changed. We're told they talk and text all the time and in the last month they've seen each other frequently.

It's a pretty clear sign ... Kourtney's history.

Shia LaBeouf took a break from his usual pasttimes -- getting arrested, getting hospitalized or just acting crazy -- to make out with his girlfriend Mia Goth Wednesday in L.A.

Love doesn't just move mountains. It keeps you out of handcuffs ... sometimes.

Looks like a Super Bowl champ might be getting Cookie's nookie -- 'cause "Empire" star Taraji P. Henson was spotted on a romantic stroll down in Miami ... with NFL player Kelvin Hayden.

The couple seems to be going public with their relationship ... being snapped by photogs holding hands and looking very much into each other.

Hayden helped secure a ring for the Colts in 2007 -- with a 56-yard INT return for a TD -- but lets be honest ... THIS is his biggest victory yet.

12:51 PM PT -- No romance here people ... sources close to the couple tell us the two are "just friends" and had a nice platonic dinner last night.

Too bad ... they'd be cute together.

Courteney Cox and Will Arnett broke bread and lobster claws Tuesday night, and there seems to be a little dating smoke.

The famous couple arrived together at The Palm restaurant in Bev Hills and had a long dinner.

At around 11 PM, Courteney left alone and got in her SUV, which took off but stopped 20 yards down the road. Will then surfaced and began walking toward the SUV and then beelined it back inside The Palm.

We're told Will eventually left by Uber.

Ruby Rose may have a new chick ... with a Justin Bieber connection.

Rose and singer Halsey took in a screening of 'Star Wars' Monday afternoon in Hollywood. They haven't confirmed they've hooked up but it sure seems that way.

Halsey sings on Bieber's new song, "The Feeling" and she's one of Scooter Braun's proteges.

They've been spotted out together before ... Halsey posted a pic with Rose a few weeks back ... a nanosecond after Rose and her fiancee broke up.
