Scott Disick's 18-Year-Old Chick He's NOT My Boyfriend!!!

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.

The second problem Lindsay has ... explaining the pics where she's all nuzzly with Disick. She says the pics are "misleading."

SOBER FLOW
TMZ.com

Justin Bieber's famous pals are coming to his defense, saying the pop singer hasn't hopped off the sobriety train despite recent footage showing him smoking and boozing.

Riff Raff tells us he and Diplo were hanging with Justin just last week in Hollywood. Riff and Dip were working on music for Raff's upcoming LP, "Pink Panther." Riff Raff freely admits, he and Diplo were "f**** up," but Justin didn't touch anything -- weed, alcohol, nothing.

Riff Raff says after the session they hit the town to party and Justin was stone cold sober the whole time. The video shows Justin and Riff Raff in the car on the way to the clubs, and Biebs looks clear-headed.

As for Justin's boozing and smoking onstage in New Zealand just a few days later, Riff Raff says he may have fallen off the wagon that night, but he believes it's a one off.

Zayn Malik's Ex Diamond Ring Trolls 1D & Little Mix Fans

Zayn Malik's ex-fiancee Perrie Edwards looks like a desperate chick who's still longing for the guy who dumped her in a new Little Mix music video -- but we've learned it's not what it seems.

The vid for "Love Me Like You" dropped Friday, and fans instantly noticed the engagement diamond on Perrie's finger. People were wondering why she was still wearing it, since they broke up 2 months ago. Was it a dig at Zayn or wishful thinking?

It's neither. We found out the video was filmed around 6 months ago, when Perrie and Zayn were still a thing. Sources who were on the set tell us she kept the ring on during shooting because they were very much in love.

But y'know ... things change. The former One Direction singer broke things off in August, and Perrie didn't take it well.

Silver lining: Perrie gets some pub for her new song.

Pope Francis I Don't Support Kim Davis

The Vatican is using the "smoked but didn't inhale" excuse when it comes to Pope Francis' meeting with anti-gay county clerk Kim Davis ... acknowledging their meeting but denying there was any exchange of support.

Davis, who was jailed for not granting same sex marriage licences in Kentucky, told reporters the Holy Father was in step with her stance, and told her to "stay strong."

Now the Vatican is saying the meet and greet between the Pontiff and Davis was so brief, the Pope never discussed the details of Davis' complex situation.

A Vatican spokesman says there were several dozen other people in the room, so Davis was not granted a "real audience" with Pope Francis -- and "his meeting with her should not be considered a form of support of her position."

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.

Selena Gomez broke her long-standing silence with the paparazzi ... to kinda sorta flirt with our photog.

Charlie and around 20 other photogs were at LAX as Selena arrived, when he asked in his discernible Aussie accent for whom she wanted to look good ... playing off her song, "Good for You."

Selena -- who is blazing hot -- didn't say Bieber. She didn't say Orlando Bloom. What she said has given Charlie tragic false hope.

Kate Hudson And Nick Jonas Guess What We're Doing Together?

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.

The people we spoke with who know them say they're not dating, but they've absolutely hooked up.

Lane Kiffin NOT FIRED AT ALABAMA ... Despite Banging Rumors

With crazy rumors circulating about Lane Kiffin ... the University of Alabama says there is one thing that is certain -- he's STILL the offensive coordinator for the football team.

Kiffin's name is blowing up on social media today ... over completely unverified rumors that Kiffin was involved in an affair with a high profile Alabama lady.

One of the rumors was that the alleged banging set off head coach Nick Saban -- who gave him walking papers.

But TMZ Sports spoke with Josh Maxson, the director of communications for Alabama football, who tells us Kiffin is "obviously" still employed and remains the team's offensive coordinator.

Maxson also told us he didn't want to comment on any "stupid" or "crazy" rumors.

Kylie Jenner's Best Friend 'Happy Birthday N****'

Kylie is taking heat for the frosted message, but she now says the cake pictured below is the one she got ... not the one above.

HOW COULD COOKIE DO ME LIKE THAT?

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?

ENGAGEMENT HINT?
SnapChat

Kylie and Tyga are finally ready to tie the knot ... at least that's what one video suggested -- but Tyga might've just been brushing up on his impressions.

Kylie posted a video to her Snapchat on Wednesday of her bf Tyga and it sounds like he says, "I don't f*** with nobody, it's just me, my fiancée, this lil' dog I just got" ... making it seem like he and Kylie are engaged.

However, if you dig a little deeper -- Tyga posted a video earlier in the day of an old interview with rapper Logic saying almost the exact same thing.

So we're callin' shenanigans.
