The Kardashians

Scott Disick was a wild man in Vegas, scoring a big fee for hosting Friday night festivities at 1OAK.

Disick, you know, bailed on rehab a week ago because he said he had business obligations. Before he left his cushy Costa Rican facility, he partied at 2 nightclubs. He kept it going last night.

No evidence Disick, who famously has problems with alcohol abuse, was boozing it up in the club.

You hear Disick scream in the video, inviting clubgoers to orally pleasure his friend.

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.

Scott Disick took a break from partying, rehab hijinks, and then partying some more to spend time with two of his kids, Mason and Penelope.

Disick and the kids hit up a sushi joint Tuesday in Calabasas.

Disick bailed on his trippy Costa Rican rehab this week and came back to L.A., but not before some serious Costa Rican clubbing. He's already booked a club appearance in Vegas for this weekend at 1 OAK in The Mirage Hotel & Casino.

Kim Kardashian's former BFF Blac Chyna did something shocking by standing up for KK in the family feud with Rob -- even though she's pissed Kim's little sis swooped and scooped her ex.

We got Blac Chyna outside Greystone Manor Sunday night, and asked how she felt about Rob Kardashian comparing his sister to "the bitch from Gone Girl." We fully expected her to pile on ... especially since she and Kim had a falling out when Kylie Jenner started dating Tyga.

You gotta see this clip ... because at first it seems like BC and Kim signed a peace treaty. But when we ask if they're friends again -- the temperature plummets 20 degrees.

Scott Disick couldn't even last a week in his posh rehab facility down in Costa Rica -- but he's killing it on the local nightclub scene.

If Scott's alleged rehab plan is starting to smell a little fishy ... that's only because it is.

Scott Disick's officially ditched rehab in Costa Rica ... so he can spend quality time at the local nightclubs.

Disick was spotted hanging near the bar in a club called Rouge on Saturday night. Sporting a black tee and ball cap ... Scott seemed like he was trying to keep a low profile -- but hanging with a big bodyguard in purple ain't exactly inconspicuous.

Witnesses tell us he also hit up a spot called Vertigo.

TMZ broke the story ... Scott bailed on the Costa Rican rehab program after less than a week. He's coming back to the states, and already has club gigs booked back here.

After we posted our story, Scott posted (and then deleted) a photo touting his upcoming appearance at 1OAK in Las Vegas.

Dr. Drew believes Scott Disick is in far worse shape than anyone believes, because his choice of rehab is dangerous, generally used by heroin addicts, and he's destined to relapse.

The good doc was at LAX Sunday when our photog asked about Disick's decision to leave the Costa Rica rehab facility Monday, after only one week of treatment. Scott says he has pressing business in L.A., but Drew says it's a common rich-people's avoidance technique.

1:30PM PST: Rob has now followed the family back on Instagram, including Kim.

Rob Kardashian clearly hates his sister Kim, comparing her to Amy Dunne, the sociopath from "Gone Girl" who killed her ex-boyfriend.

Rob just posted this pic on his Instagram, and it's really shocking. He's been MIA for months, but he's now re-surfacing in a big way.

Rob also just un-followed his entire family from Instagram.

You'll recall Rob bailed on Kim's wedding in Italy just before the photo shoot, and it seemed at the time there was bad blood, but that blood is clearly boiling now.

Scott Disick has decided he's too busy to stay locked down in rehab ... we've learned he's bailing on the facility in Costa Rica.

Sources close to Scott tell TMZ ... Disick had actually booked a flight Saturday to LA but he didn't get on the plane. Scott entered a rehab facility in Costa Rica last Monday, where he was undergoing an intensive therapy involving the African psychedelic shrub Iboga.

Disick's people tell us he decided not to take that flight but will leave that facility Monday because he has too much business in LA to deal with. As for why he didn't get on the plane today, we're told he wanted to complete a full week of treatment before bailing. The normal length of treatment is three times that -- 21 days.

We're kinda tired of solving this mystery, so we'll leave it to you. Is Kim Kardashian that fickle that she'd change her hair color twice in the same month, or is wearing a wig?

This pic was taken Friday in Calabasas. It paints a dark picture of Kim K ... this, just weeks after she became blonde during Paris Fashion Week.

Check out this pic Kim posted with her photographer, Ellen von Unwerth. BTW, Ellen specializes in "erotic femininity."

Now that we think about it, screw the hair. What's Kim up to now?

Kris Jenner's now tailing other people's famous kids around the world -- instead of her own -- and her latest target is "Fifty Shades of Grey" star Dakota Johnson and her mom, Melanie Griffith.

Jenner is currently third wheeling it with DJ and Mel on their Mexican vacation. Despite being 30-plus years older than Dakota ... the moms are right next to her, proudly flaunting their bikini bods too.

The Kardashian matriarch also hung out with Lindsay Lohan in Paris earlier this month during Fashion Week.

Hey, at least when you hangout with other people's kids ... you don't have to pretend to parent them.

Scott Disick is finally addressing his substance abuse problems ... by taking a fabulous psychedelic trip into the Costa Rican jungle! Sound like groovy fun? Well, it's actually serious therapy, man!

But also most likely ... pretty groovy.

17-year-old Kylie Jenner donned a revealing bathing suit during a photo shoot in the Hollywood Hills on Tuesday ... and did we mention she's 17?

Last week, Kylie's 25-year-old boyfriend Tyga finally confirmed their relationship by posting a pic of 17-year-old Kylie with the caption, "Certain things catch your eye, but only few capture the heart."

It's unclear where the pics from this photo shoot will end up getting published, but we'd suggest ... Seventeen magazine.

Fun fact: Kylie Jenner is only 17-years-old.

Scott Disick is fed up with traditional rehab treatments, so he's taking an all natural option -- as in sucking down hallucinogenic plants in the jungle ... under the supervision of a shaman, of course.

As we reported ... Scott checked into the Rythmia Life Advancement Center in Costa Rica, where we're told they use the African psychedelic shrub Iboga to send patients on a vision quest.

Hang with us ... it's about get even trippier. These "Iboga flights" are supposed to force users to examine their inner selves so they can learn what triggers their addictions. Sources connected to Scott tell us a shaman observes the entire trip, and the center says it's so effective ... it boasts a money back guarantee.

We're told Disick briefly visited the facility last month to research the place and was convinced Iboga could help him fight his alcohol demons.

Treatment can take several weeks, or as brief as one week -- but that would be one helluva trip ... we're guessing.

Bruce Jenner is continuing his ride to transform, because we've learned a few weeks ago he got a nose job to smooth things out.

Sources close to Bruce say the goal was to "soften" his features and make his nose look more feminine. Must say ... it worked.

It's the latest in a series of physical changes, that included a laryngeal shave to smooth out his Adam's Apple.

As we reported Bruce has also been undergoing hormone treatments and has been undergoing therapy for the transformation ... therapy that has been going on for years.

Scott Disick has decided to go to rehab, after an insane, tequila-fueled weekend.

Disick checked into Rythmia Life Advancement Center in Costa Rica. He says, "I realize my issues are bigger than me and I'm ready to truly remedy this struggle I continue to battle."

Scott was in Atlantic City over the weekend where he did multiple shots of tequila right out in the open. He then went on a rant onstage and ended the night at 8 AM, where he was stumbling in the hotel lobby without shoes. At 5 PM people went to his room to do a welfare check when he was MIA.

Scott has had multiple problems with alcohol and has vowed to maintain his sobriety, especially after his girlfriend Kourtney gave him an ultimatum.

As for his treatment, he says he is doing Iboga treatment, which involves roots from a small African tree that supposedly helps people battle addiction.

As for the facility, Rythmia is located on a private estate offering a "luxurious world-class experience" including a five-star restaurant, full-service spa with mud bath, and fitness center.
