The Kardashians

French Montana knows knows how to walk a tightrope ... skirting the issue Kanye raised in song ... whether someone married to a Kardashian thinks about banging the other Kardashians.

We got Khloe's ex Friday night at LAX, and asked him if Kanye's verse -- that he has thought about what it would be like to have sex with Kim's sisters -- was disgusting or understandable.

Younes Bendjima's flying solo now, and because of that ... it appears his mode of transportation's a lot more basic than what it used to be.

Kourtney Kardashian's ex-bf was spotted out by himself in WeHo Thursday in very casual attire, before hopping in a ride worth hundreds of thousands less than Kourt's convertible Bentley he was seen gassing up in Calabasas last month ... a regular ol' Ford Explorer.

The 25-year-old model has been getting back to a normal way of living since Kourtney dumped him a few weeks ago ... possibly because he cheated on her.

'Vanderpump Rules' star Jax Taylor pointed it out to the world when he spotted Bendjima slumming it at the regular gym Monday night just like him ... with some regular water.

Kim Kardashian West is teaching her kids how to live it up in Miami ... which should always include some time spent on a luxury sea vessel.

KKW brought her oldest children -- North and Saint -- onboard Miami mogul David Grutman's yacht Thursday ... and had her finest hot pink, skin-tight Chanel catsuit on to chase 'em around.

North matched her mom with some pink shorts, and Saint looked absolutely adorable rocking a captain's hat.

Also on the yacht were family friends Jonathan Cheban, Larsa Pippen and her daughter Sophia.

Here's Kim Kardashian West just trying to stay low-key and under the radar in Miami and ... JUST KIDDING, SHE WANTS ALL THE ATTENTION!!!!

With the boobs out and the dress short, KKW shined bright like the sun in a tight, canary yellow Versace mini dress while vacationing in Miami this week.

37-year-old Kim was leaving a fancy dinner at Komodo with a pretty solid squad -- Larsa Pippen, Jonathan Cheban, David Grutman and Isabela Grutman.

The Kardashian West fam just got back to the States after spending some time in the Bahamas -- where her 2-year-old son, Saint West, grooved to Petey Pablo's old hit, "Raise Up."

Start 'em young, Kim.

Blac Chyna thinks little Dream is a spitting image of her and not baby daddy Rob Kardashian ... but we gotta ask ... really???

We got BC Wednesday night heading into Project LA in Hollywood and she didn't hesitate on the issue of likeness -- Dream's a chip off the old mom block.

Rob's got a ton of recent photos of their almost 2-year-old up on social media, and her features are certainly starting to get much more defined. As for Chyna's claim ... we really can't say. Truthfully, Dream looks a little like both of them -- they each technically contributed half of themselves, after all.

How about we just stick to the custody deal in place here and call it 50/50? That ... or you can just weigh in for yourself. Either way ...

Kris Jenner still loves Kanye West ... even if he does fantasize about getting with her daughters, despite being married to Kim.

We got Kris and her mom leaving Nate'n Al deli in Beverly Hills Wednesday, and asked if she has any thoughts on Kanye's new track ... in which he revealed he wants to "smash" all 4 of his sisters-in-law.

Kris seems to find it all kind of funny, and says she's got nothing but love for Ye ... so, not your typical mother-in-law response.

Khloe Kardashian just popped a baby out 4 months ago -- but you would never have known by the way she looks now.

Khlo's still in Mexico this week with Tristan Thompson, and on Monday she took a stroll on the beach solo in a body-hugging one-piece. All we can say is DAYYYUMM (*smokey voice*).

She's definitely embracing her revenge body philosophy from last year, only now she's got a hot mom bod twist on it ... from the front and the back. Lordy, that's a whole lot of booty.

True story ... Tristan's got one hell of a woman on his hands here, and he should count himself lucky that she didn't curve him after his cheating scandal earlier this year.

She's certainly curving everything else ...

Khloe Kardashian and Tristan Thompson still haven't come up for air ... 'cause they're still sucking face in Mexico with Kendall Jenner and Ben Simmons in tow.

Khloe, Tristan, Kendall, Ben and a bunch of friends hit up the popular resort town of Puerto Vallarta, Mexico where we're certain there's TONS of action ... based on the pics -- a little swimming in the pool, a dip in the ocean, some jet skiing and PDA-packed sessions.

Khloe Kardashian and Tristan Thompson stuck out like a sore thumb (or a green thumb?) this weekend in Mexico -- partly due to wardrobe ... not to mention the company they kept.

The two parents were partying at La Santa nightclub in Puerto Vallarta -- sans True, of course -- very early Saturday morning, where Khloe wore a bright green highlighter dress ... and Tristan stood at his usual 6'9". Safe to say, you couldn't miss 'em if you were there.

Speaking of which ... one guy who definitely didn't pass up a chance to chat the couple up was 'Girls Gone Wild' founder Joe Francis. He was hanging out as well.

The Kardashians -- and tons of other celebs -- have been known to frequent Joe's nearby Punta Mita oceanfront estate. He reportedly hit a snag last year though after a judge ruled he couldn't profit off the property anymore due to alleged fraudulent activity ... but Joe's refuted that saying "It is business as usual at Casa Aramara in Punta Mita Mexico."

Kanye West's new song says he's got "sick thoughts" ... and some of them involve all 4 of his sisters-in-law.

Ye released a brand new track Saturday morning on Twitter -- "XTCY" -- and along with obvious lyrics about ecstasy ... there's a very interesting line about wanting to bang Kim's sisters -- Kourtney, Khloe, Kendall and Kylie.

West raps ... "You got sick thoughts? I got more of ’em / You got a sister-in-law you would smash? I got four of them." Then he says they need a bigger hot tub.

Kanye's been very open about his sexual fantasies this week, including talking to Jimmy Kimmel about what kind of porn he prefers ... which led to an offer to direct his own adult film.

Kanye West just got an offer he might not refuse ... directing a porn movie after giving his fav a shout-out on "Jimmy Kimmel Live!"

Greg Lansky -- widely considered the Steven Spielberg of porn -- runs a high-end porn production company, including Blacked.com, which also happens to be Kanye's XXX of choice. The rapper said as much to a late night national TV audience.

Didn't take long for Greg to craft an offer and fire it off to Ye ... first thanking him for mentioning Blacked. As for the offer -- let Kanye direct a porn movie. According to the letter -- obtained by TMZ -- Kanye will have full artistic control.

And, how's this for an enticing offer? Greg also has 2 porn stars in mind for Kanye's film.

If the Blacked.com deal doesn't do the trick for Kanye -- Pornhub's got his back (and his front) too -- telling us they'd like to extend a free lifetime membership to the site's HD, on-demand streaming service, Pornhub Premium.

Kylie Jenner is no stranger to flowers or cash ... so clearly nothing makes more sense than to gift her a gigantic solo cup made of roses ... which comes with a hefty price tag.

Jenner showed off the creation from La Fleur Bouquets Thursday -- a 21st birthday gift she got from her friend, Yris. We're told the "Legal AF" solo cup was made with more than 1,000 real roses -- and comes in right around $5,000.

The arrangement was just one of several gifts Jenner got for her 21st, not to mention the gigantic party she threw at Delilah in West Hollywood ... with guest that included her fam, along with Bella Hadid, The Weeknd, Dave Chappelle and baby daddy Travis Scott.

Kylie Jenner can legally drink -- and she's a billionaire -- which are 2 good reasons why there were 2 insane parties Thursday night that not only brought out the Kardashian brood in full force, but reunited Scott with Kourtney and Caitlyn with Kris ... at least for one night.

You gotta see the video. Hoards of photogs pounced on Craig's in WeHo Thursday night, as Kris, Kim, Kanye, Kendall, Kourtney, Scott and Khloe made their way in.

Caitlyn, who has been estranged from most of her former fam, made a rare appearance ... partly because she still has a relationship with Kylie.

It was more than a family birthday celebration ... Dave Chappelle, Chandler Parsons, Kevin Durant, Paloma Ford, Meek Mill, Chris Brown and French Montana were on hand for the bash. Bella Hadid and The Weeknd were also there together.

It didn't end at Craig's. The party moved to Delilah, where everyone cut loose. Chappelle grabbed a mic and sang, "Killing Me Softly."

There's nothing in this world that can stop Kanye West from watching porn ... not even his 2 daughters or his smoking hot wife.

Kanye made no bones about it ... Ye proudly revealed on 'Jimmy Kimmel Live' that he still watches X-rated films.

Kanye's favorite XXX category? "A lot of black on white, obviously." Sounds like Ye can't get enough of Kim Kardashian West ... in the bedroom or in his fantasies.

Ye has been a father for five years, but it doesn't sound like North West or Chicago West will ever be able to stop their daddy from cranking one out to some good, old-fashioned porno.

Kim Kardashian West did a shameless promo ... for gravity and, if you weren't before ... you're about to be a big fan of it.

Look, we're not trying to score a Pulitzer here. It's Kim. It's a white bikini -- a small bikini -- a trampoline, and umm ... that's it, really.

Although we definitely do NOT want to undersell the miraculous work put in here by Kim's bikini. The fabric is holding everything in place.

Kourtney Kardashian channeled Kool & The Gang with a ladies' night post-Younes Bendjima -- and then she channeled 'Fast & the Furious' ... emphasis on the furious.

Kourt hit the town Wednesday with her good pal, Larsa Pippen, who joined her at Madeo in Bev Hills for some grub. As they were leaving, paps lit up like a bunch of hungry seagulls -- ourselves included -- and peppered the eldest Kardashian about her split with Younes.

She was tight-lipped on her feelings about the dude, but was a little more fast and loose with her steering wheel while trying to get the hell outta there.
