The Kardashians

Tyga and Kylie Jenner were out together Monday night ... and we're told it was a date, but the way "date" is defined is, well, a sensitive issue.

The youngins went to Kabuki restaurant in Hollywood. Sources close to Tyga tell us they are "dating" but are quick to add that does not mean they are physical. It's important, because he's 24 and she's 17.

One Tyga source told us ... if we even insinuate they are having physical contact he will deny he's dating Kylie ... even though the source says Tyga privately says he's dating her.

BTW ... sitting on the same side of the booth is prima facie dating, right?

Baby North West has a couple of interesting toys -- doll versions of her famous parents -- and they are the spitting image of Kanye West and Kim Kardashian, right down to her hips.

Bruce Jenner changed his look up for the Elton John concert in L.A. Saturday night.

B.J. went to the show with his son Brandon Jenner and Brandon's wife. Another random girl tagged along ... but no word on who she is ... or if it was any sort of date.

Bruce and Kris Jenner made their split official last month when Kris filed for divorce.

In case you haven't been to an Elton John concert ... that's the place you let your ponytail down.

The man who attacked Jonathan Cheban with a knife 4 months ago was shot and killed by NYPD officers Friday after a tense standoff.

Police say Denis Volchkin had ransacked his mother's home in Brooklyn and when officers arrived he was sitting on a couch with 3 knives next to him. Cops tried to talk him into surrendering, but he eventually lunged at them with one of the knives ... and they opened fire.

Volchkin was hit once in the body, and died later at a hospital.

Law enforcement sources, and Cheban himself, tell TMZ ... Volchkin is the same man who lunged at Jonathan when he was in a Brooklyn sushi joint back in May.

TMZ broke the story ... the "Keeping up with the Kardashians" regular was leaving the restaurant after Volchkin -- who had a knife on him -- tailed JC around the spot. When Volchkin made his move, Cheban's bodyguard punched him in the face and subdued him.

Selena Gomez takes one trip to Paris and suddenly she's a changed woman ... who's apparently settled her blood feud with the Kardashians -- and proved it by giving Kris Jenner a ride home.

Selena was swarmed by photogs late Wednesday afternoon as she came home from Paris Fashion Week -- and just as her SUV was pulling away the big shocker happened ... Mama Kardashian jumped in the backseat with her.

As we told you ... Selena had a major falling out with the Ks after Coachella ... blaming them for her out-of-control partying.

Remember, while she was in Paris she also posed for pics with Miranda Kerr -- who allegedly hooked up with Justin a few years back.

Kendall Jenner is officially on the A list of models after waking the Chanel runway in Paris alongside none other than Gisele Bundchen.

Yeah, looks like the young'uns are gunning for GB and TB -- 'cause Tom Brady's suddenly NOT the biggest hunk QB in the NFL ... or even in New England! Hope their finances are in order.

Justin Bieber just left a big fashion party in Paris that was filled with celebs ... and we're told the Biebs made sure he didn't cross paths with the modern version of Helen of Troy -- Miranda Kerr!

Justin hit up the CR Fashion Book Party and mingled with Kim Kardashian, Kendall, Kris, Paris Hilton and Selena Gomez. Our spies say Justin was gushing about Selena, telling people how beautiful she is and how they're really tight now. So the whole champagne dinner with Kendall was innocent.

Justin Bieber and Kendall Jenner giggled over a champagne dinner in Paris Tuesday night ... which raises the question, huh?

Justin is in Paree with Selena Gomez. In fact, they were spotted eating breakfast earlier in the day.

Bieber picked Kendall up at her hotel in a Rolls and drove her alone to the popular Ferdi restaurant.

Here's why it's especially interesting ... Selena doesn't like the Jenner girls. You'll recall .. after Coachella Selena cut off all ties, calling the Jenner girls toxic.

As for Justin and Kendall ... her people say they're just long-time friends. So, do you believe them?

Hard to deny Kendall Jenner's place in the fashion world now that she's walked the runway at the Chanel show during Paris Fashion Week -- but is she really worthy of such a gig?

Kendall was in great company -- highest paid model in the world Gisele Bundchen was also in the show ... so, pretty impressive for the 18-year-old. She's only been in the biz for a short time, and some say she only gets high-profile jobs because of who she is.

Kim Kardashian was ready for an encore performance from the dude who almost knocked her to the ground during a Paris Fashion Show event ... the guy tried again and this time he FAILED.

Kim and Kanye West were having dinner at Hotel Costes in Paree at 6:00 PM -- a sign of age, right? -- when her security team eyeballed Vitalii Sediuk ... the guy who tackled her Thursday.

This time Kim and Kanye's beefed up security team jumped into action, surrounding him and keeping him far from his target. By the time they let him go, Kim and Kanye were long gone.

Vitalii is still on the loose ... he didn't commit a crime so there was nothing that could be done to him. As we first reported he wasn't arrested by Paris police after the fashion show attack, because cops say it was a stupid, nothing offense and they had better things to do.

Kanye West is protecting his gluteus to the maximus.

Kim and Kanye are in Paris for Fashion Week and Mrs. West posted a picture on Instagram of Yeezus showing his affection for her backside.

As we previously reported ... Kim upped her security detail this week after she was almost tackled to the ground by a crazy person during an event in Paris.

Good thing Kanye's got her ass covered.

Kim Kardashian and Kanye West got another bad reception in Paris ... arriving late to a fashion show where a couple of hecklers booed them.

Kim -- who FYI wore nothing underneath her blazer -- and Kanye showed up at the Lanvin fashion show after it started ... and as they walked to the front-row, several dudes staring booing them.

Kanye gets defensive -- dropping the name of Alber, the designer throwing the shindig -- saying he wanted to see them ... implying they were only late because they were backstage talking to the designer.

Did we mention Kim's boobs?

Parisian police couldn't care less Kim Kardashian was attacked while making her way through paparazzi at a Fashion Week event ... they say the assault means nothing to them ... and don't understand why Americans make such a big deal of it.

An official from the Prefecture de police de Paris said unlike the cops in the U.S. ... the Paris police don't become involved in such "minimal situations."

So cops tell us they will take NO action against Vitalii Sediuk for trying to tackle Kim to the ground.

It's a pretty laissez-faire attitude ... considering Princess Diana was killed in Paris 17-years ago while trying to flee from paparazzi.

As we previously reported ... Kim and Kanye beefed up their security while in Paris.

Sacrebleu!

Kim Kardashian and Kanye West are bulletproof -- or will be very soon -- because they're ramping up their personal security -- complete with ARMORED VEHICLES -- after a frightening assault in Paris.

Our Kim and Kanye sources say ... K&K were "freaked out" after Kim was almost tackled to the ground by a crazy man. They're especially upset because the Paris paparazzi are following them in hordes ... and crowd control has become extremely difficult.

Our sources say ... they've hired 2 additional teams of armed bodyguards who will encircle them whenever they're in public during Fashion Week.

We're told Kim and Kanye will NOT retain the additional security when they come back to the U.S. They feel Paris has just become too insane for them to handle.

Kim Kardashian was tackled and almost knocked to the ground in an alarming assault during a Paris Fashion Week event.

Kim, Kanye and Kris Jenner arrived at a fashion show Thursday ... and several hundred people -- including a gaggle of photogs -- were squeezed in to watch them arrive.

As Kim gets out of the car, a guy lunges at her, tackling her legs and tries to pull her to the ground.

You see security jump in, subdue the guy ... and then quickly escort Kim and Kris into the building.

TMZ has learned the attacker may be Vitalii Sediuk -- the Ukrainian prankster who did the same thing to Leo DiCaprio, Brad Pitt, and Will Smith. According to his rep, Sediuk is taking credit for lunging at Kim.

Once again preparing to bless the world with another Spawn of Disick, Kourtney Kardashian showed off her pregnant body while lounging poolside in Los Angeles.

This will be the third child for KK and SD -- they already have son Mason, 4, and daughter Penelope, 2.

Kourtney told Scott she was preggers on the season premiere of "Keeping Up With the Kardashians" and his reaction was amazing.
