Hook Ups

Scott Disick's 18-year-old travel companion says she's NOT sleeping with or dating him ... at least that's the story she's telling her friends.

Lindsay Vrckovnik insists she's never hooked up with Scott. She says she's been traveling with a group of models and met Scott in NYC, and hung out for a day. The girls wanted to move the party to Miami over the weekend, and according to what she's telling friends ... Scott happily followed.

Lindsay -- who's from Canada -- has a boyfriend there and the photos that surfaced have caused a problem between the two of them.

Whatever Lindsay claims ... she's having trouble convincing her BF for a few reasons. First, she and Scott didn't meet for the first time last week ... they hung out at least once before, in July, at a party in Malibu.

"Empire" star Jussie Smollett is keeping it as real as his TV mama Cookie does ... saying he's NOT hookin' up with Michael Sam ... despite the fact they've been spending A LOT of time together recently.

Two weeks in and Rita Ora and Travis Barker are already acting like they've been living together for years.

The new couple rolled out of bed Sunday for brunch in West Hollywood, and it looks like she went shopping ... in his closet. Barker's grungier style is clearly rubbing off on the "Black Widow" singer, who usually opts for less cover up.

As we told you, they've been inseparable since first hooking up at a charity basketball event last month ... she's even been staying at his West L.A. home every night.

Scott Disick took his new girlfriend across state lines ... from New York to Florida.

Scott and 18-year-old Lindsay Vrckovnik were having fun in the sun in Miami Friday, showing skin, nuzzling and soaking in the sights. Lindsay's got some nasty bruises on her legs.

They spent a day or so in NYC the day before, where Scott showed Lindsay around.

Future and Blac Chyna were definitely together Friday night in D.C., and it's pretty clear now they've hooked up.

Future had a concert at Echo Stage ... then went to his after-party where Chyna was right by his side.

We're told they were there for around an hour ... never apart.

Future and Chyna left together at 4 AM.

'Nuff proof?

Scott Eastwood and Charlotte McKinney seemingly confirmed what has been floating around for a while now -- they're totally banging.

The two were seen walking barefoot in Malibu on Thursday and they look pretty comfortable together.

Rumors of the two being in a relationship have been swirling for some time and this looks like the icing on the dating cake.

Scott Disick just took his talents and his relationship with blonde model Lindsay Vrckovnik to South Beach.

They started hanging out in New York this week, but looks like Scott's gonna hang on to her for at least a few more days ... since their all-nighter turned into a weekend getaway.

32-year-old Disick and the 18-year-old model, who just graduated high school (congrats!) were in Miami cruising from the schmancy Setai Hotel to the beach.

We're told Scott was very flirty with his new lady friend, and spent hours on the beach together.

At least he's spending time with a kid ... just not his own.

Sorry Vito ... Michael Sam is finally moving on -- 'cause the football player hit up his old stomping grounds at the University of Missouri yesterday and declared, "I might try to find a husband in here."

Sam was doing his first Periscope with his friend L'Damian Washington and decided to livestream from the campus of UM while talking to various students.

While walking into one of the buildings, L'Damian says, "I might find my wife today."

Sam retorts, "I might try to find a husband in here."

Seems to be the first time Sam's acknowledging that he's moved on from his longtime BF/fiance Vito Cammisano ... after breaking up over the summer.

There was one other interesting thing that happened during the Periscope sesh ... Sam asks a woman if she'll be the mother of his kids -- and she says yes.

Seems Karrueche Tran's summer lovin' is spillin' over into the fall ... because she's getting very close with Manchester United star Memphis Depay ... and even went to his game Wednesday night.

Tran was first spotted with Depay in Miami back in June -- but recently it seems things have started to heat up ... with the two hitting nightclubs together and even shopping in Manchester.

Now, with Tran attending the Man U game ... pointed out by our friends at BSO ... it's just another clue she's more than just friends with the guy who signed a $40 million contract back in May.

BTW, Man U won the game 2-1 ... and even though Memphis didn't score on the pitch, seems he might do pretty well after the game.

"Big Brother" stars Austin Matelson and Liz Nolan are shattering the taboo of reality show romance ... much to the dismay of a torrent of online haters.

Austin tells TMZ when Big Brother ended ... he was flooded with messages calling him a "disgusting cheater" and "classless" for breaking up with his then-GF on TV.

For the non-fans ... Austin and Liz kicked off a relationship early in the show ... despite the fact that Austin was a taken man.

They both got called out for the love triangle ... in one of the most awkward moments of the season.

Austin says, he and Liz are now exclusively dating, have met each other's families and Liz plans on moving from Miami to LA to be close to him.

Love is cool ... but $500k would have bought a lot of friends.

Kate Hudson and Nick Jonas say they're not dating ... but does hooking up count?

The 2 were all over the place -- together -- this weekend, first at Disney World in Orlando and the next day at brunch in Miami.

Kate -- who's 36 -- went to Nick's show at the House of Blues in Orlando Saturday night. Oh, right, he's 23.

It kinda makes sense. She was probably his jam growing up, and she's still just as hot.

Taraji P. Henson and the "Empire" writers should know ... 50 Cent doesn't sweat people taking shots at him -- been there, done that -- so, he's firing right back with a direct shot at Cookie's ... cookie.

During the "Empire" premiere ... Taraji's character made a crack about Fif being "thirsty," and it didn't take long for him to respond.

Check out the video -- 50 wants everyone to know he's got a sexual past with Cookie.

So, is it just faux TV beef, or is Fiddy really talking about Taraji? We're guessing it's door #1.

But who really knows?

Jaden Smith's got himself an older woman, and he's showing her off all over NYC.

17-year-old Smith was out with his 19-year-old girlfriend Sarah Snyder in SoHo on Wednesday after attending a NYFW show. Snyder is a social media fashionista with a ton of followers.

Reports say the two have been together for a few months and judging by the pics, the youngins are getting pretty comfortable with each other.

We know what you're thinking ... age of consent in NY State is 17.

BTW -- if Sarah looks familiar -- it's because she was arrested in NY for allegedly stealing a $16,000 Hermes Birkin bag back in June.

Travis Scott is a real kiss and tell kind of guy ... or he's just under Rihanna's spell.

Scott had a show in Santa Ana, CA Monday night when he let the entire sold-out crowd know just how lucky he's getting with Rihanna. Scott cleverly switched up the lyrics to his track, "3500."

The original lyrics are, "One time for the trill bitches that'll let me touch it.”

But watch at about 13 seconds you'll hear ... "One time for the RiRi that'll let me touch it.”

This video ... combined with their recent make-out sesh at NY Fashion Week ... should convince doubters RiRi and Travis are the real deal -- or maybe it just looks like a giant PR stunt.

One little U.S. Open loss isn't gonna break Serena Williams and Drake -- they went extremely public with their relationship at her fashion show in NYC.

The PDA went down right after Serena's Fashion Week event ... and not only did they share a kiss on camera -- his lips to her hand -- but she also used a bunch of his songs during the show.

Here's the thing though, you really gotta see how these 2 are staring into each other's eyes backstage.

Rihanna and Travis Scott were like two dogs in heat early Friday morning at her Fashion Week after-party ... making out, grinding and dry humping each other as if no one was watching.

Fact is ... they were openly and notoriously affectionate in front of a room full of people.

The two have been hanging out in NYC this week, fueling rumors they've hooked up ... but this video pretty much confirms it.
