The Kardashians

Kim Kardashian and Rita Ora ended up on the same flight out of Los Angeles Monday, which wouldn't be a big deal ... until you remember Kim has MAJOR BEEF with Rita!!!

As TMZ first reported, Kim still blames Rita for her bad breakup with Rob Kardashian ... which she considers the cause of a lot of his problems since then.

Things are still so bad between them ... Kim refused to sit near Rita at the VMAs.

Rita arrived about 30 minutes before Kim -- who was with Kanye West and North -- but they probably ended up in first class together.

Kim Kardashian gave Rita Ora the cold shoulder at the VMAs last Sunday -- refusing to sit near her -- and sources close to the family say it's because Kim blames her for screwing with Rob Kardashian's head.

We're told Kim arrived at the awards show and discovered her seat was just a couple away from Ora's. Not wanting any drama ... she asked producers to find her a different seat. We're told she wasn't a diva, she just didn't want to have to be social with Rita.

Sources close to the Kardashians tell us the family still blames Ora for some of Rob's issues ... since his ugly breakup with her in 2012.

VMA producers had to scramble, but ultimately they found a seat for Kim ... with Kendall and Kylie.

Sugar Ray Leonard celebrated his 21st wedding anniversary like a BOSS last night -- expensive dinner, expensive gift ... and it all ended with a pretty funny dig at the Kardashians.

The clip is hilarious ... the couple was clearly in a SPIRITED mood on the way out of Katsuya in Brentwood (his wife Bernadette was especially happy) ... when we asked about the gift!

At first, Bernadette plays coy ... but ultimately spills the beans about the badass (and super thoughtful) gift Leonard gave her to celebrate the occasion.

And then came the Kardashian diss -- check out the video.

Keyshawn Johnson has a message for Kourtney Kardashian -- YOUR MOLD IS YOUR PROBLEM -- telling TMZ Sports ... KK's claim that he sold her a moldy Calabasas mansion is pure B.S.

Keyshawn and his fiancee Jennifer Conrad were out in Beverly Hills -- getting ready for their wedding this weekend -- when the future Mrs. Johnson told us, "There was no mold when the house was sold. I promise you that."

Key added, "House was sold. House was bought. Everything else is everybody else's problems -- not mine."

As we first reported, Kourtney and her family are living in the Montage in Beverly Hills --claiming Key failed to disclose black mold in the master bedroom.

Key told us the house was "thoroughly inspected by excellent, experienced inspectors that they hired" before the deal went through -- and he did nothing wrong.

Kim Kardashian assumed auntie duties in Calabasas Tuesday ... taking her nephew Mason Disick to the movies.

Kim didn't have a lot to say but Mason did. He told our photog he went to see "Teenage Mutant Ninja Turtles" in The Commons. He also has a fav -- Donatello.

We're told Kim took Mason out for the afternoon so he didn't go stir crazy in the Montage hotel in Bev Hills, where mommy Kourtney, Daddy Scott and sister Penelope are staying because they claim the house they bought from Keyshawn Johnson is full of dangerous black mold.

For the average driver, pulling out of a semi-tight parking spot is nothing exciting, but when it's Kylie Jenner (aka The World's Worst Driver) it makes for riveting video.

Jenner and a friend were leaving Urth Cafe in West Hollywood Tuesday, when she retrieved her infamous Range Rover from the valet ... which was left parked between two cars ... a Mercedes SUV and a Lamborghini.

Keyshawn Johnson is enraged that Kourtney Kardashian is suggesting he defrauded her by selling her a mold-infested house.

Sources close to Keyshawn tell us he's scoffing at Kourtney's intimation he painted over dangerous black mold so it would go undetected. In fact ... Keyshawn insists he never painted a single wall during the 2 1/2 years he lived in the Calabasas mansion.

Our sources say ... Keyshawn believes the mold developed AFTER the sale when a bathroom pipe sprung a leak in the wall. Keyshawn says someone in the Kardashian klan actually reached out to Keyshawn asking if the house was still under warranty so they wouldn't have to pay for the repair.

Keyshawn is incredulous because he has 2 kids who lived in the house until the day before it was sold ... and the kids mostly slept in the master, where mold was found. He says he would never knowingly expose his kids to mold.

He also says the Kardashians have been a pain in the ass ... calling at least 10 times after the sale to ask about this and that.

Kourtney Kardashian is crying cover-up ... claiming the house she bought from Keyshawn Johnson is infested with dangerous mold that was masked by a coat of paint ... sending her family fleeing for their safety.

We're told Kourtney's decorator found the mold when he installed some fixtures.

Kourtney and the kids checked into the Montage hotel in Bev Hills Monday. The photo agency didn't get Scott Disick ... but we're told he arrived later. The family just returned from the Hamptons and decided it was too dangerous to move back into the house -- especially since Kourtney is pregnant.

Sources connected with Kourtney say she's on the attack ... ready to sue anyone who's responsible. She believes the fresh paint over what she claims is mold is the smoking gun.

We've made multiple calls to Keyshawn ... but haven't heard back.

10:27 A.M. PDT -- We're told Brody will attend the opening ... but will no longer give 1-on-1 interviews.

Brody Jenner needs to get a grip ... he's courting the media to interview him and only one thing is off limits ... the thing people care about.

Brody's promoting the opening of a Dave & Buster's in Hollywood ... and is courting the media for 1-on-1 interviews ... but we're told any talk about the Kardashians/Jenners is out of bounds.

Why he skipped Kim's wedding? ... Next question.

Why he hung Bruce out to dry on the PCH? ... Nice try.

His love/hate relationship with Kris? ... Uhhh, no.

Oh, you can ask him about the 7 "Keeping Up The Kardashians" episodes on which he appeared ... just avoid bringing up Kim, Khloe, Kourtney, Kylie, Kendall or Kris. You know, pretty much anybody else on the show whose name begins with "K."

Now the list of what's left to talk about that's interesting.

Kylie Jenner is full of BS by claiming she was rear-ended by a reckless driver Thursday ... because the other driver says she not only caused the crash but copped an attitude.

As we first reported ... the 17-year-old was driving her brand new Range Rover when -- according to her -- a woman swerved into her lane and rear-ended her.

But the woman's lawyer says what REALLY happened is that Kylie made an illegal U-ey with no warning and crashed into oncoming traffic.

The accident was so bad ... the lawyer -- Gary Daglian -- says his client's passenger ended up in the hospital.

Kendall Jenner wants to prove she's no food bill scofflaw ... which is why she not only paid for an expensive meal Tuesday -- she also left the server a big fat tip.

Kendall hit up Pearl's liquor bar in West Hollywood with Stephen Baldwin and his daughter Hailey. We're told the tab came to $554 ... and Kendall covered the whole thing ... AND left a $160 tip.

Kylie Jenner is now eligible to qualify for a demolition derby ... because she was just in yet another car crash ... TMZ has learned.

We're told the latest crash -- which occurred Thursday night as she was driving home from dinner -- resulted in thousands of dollars in damage to her brand new Range Rover.

Here's Kylie's story. She was driving home from Katsuya in Glendale when a woman in another car got cut off. She says the woman swerved into her lane and rear ended her.

The scenario is what Kylie told her parents ... so take it for what it's worth.

She has a rich, short driving history. The 17-year-old caused a multi-car crash a year ago ... 18 days after she got her license. She messed up her Mercedes SUV.

Kylie also got ticketed in January ... we're told it was for speeding.

Last month Kylie was pulled over and ticketed for tinted windows and driving with a teenager ... she's too young to have a minor alone in the car.

If you see Kylie on the road ... a sharp right onto a side street is advisable.

Kendall Jenner admits she “accidentally” walked out on a restaurant tab in NYC, but denies she threw cash at the waitress who confronted her about it.

Now that Kendall’s lawyered up and demanding the waitress apologize -- some people can't figure out who's telling the truth ... Jenner or the jilted server?? TMZ inspeculates!

Kendall Jenner claims she's been defamed by a waitress who said the 18-year-old threw money in her face ... and she's threatening to sue.

TMZ has obtained a letter from Kendall's lawyer, admitting Jenner was indeed at Mercer Kitchen last week and that she accidentally skipped out on the bill.

But legal pitbull Marty Singer says the rest of the waitress' story is a pack of lies. The waitress tweeted she chased Kendall down the street to get the money and Jenner threw it in her face.

Singer says in the letter ... what actually happened was that the waitress did come up to her outside but Jenner was "extremely apologetic" and gladly paid what she owed -- $33, plus a $7 tip ... which she "politely handed" to her.

Singer says, "Although you are working as a waitress at Mercer Kitchen, I understand you are also a struggling actress," adding, "You no doubt concocted a fictionalized account of your encounter with my client in order to create publicity for yourself."

Kim Kardashian is tired of her brother wallowing in his problems, and admits she's taking a tough love approach until he takes action.

Kim was on "Watch What Happens Live" Tuesday night and told Andy Cohen what went down between her and Rob when he left Italy before her wedding to Kanye West.

As TMZ first reported ... Rob ditched because he was self-conscious over his weight gain and did not want to appear in any wedding photos.

Last night Kim said, "I try to encourage him, and once you don't make that change for so long ... my patience wears out." She never says exactly WHAT he's been dealing with "for so long" -- but our Kardashian sources say Rob's weight gain is closely tied to his issues with drugs.

Kim, Khloe and Kourtney Kardashian are REFUSING to film season 10 of their reality show ... unless the person stealing their money and jewelry is caught.

Family sources tell us ... the girls are convinced whoever has stolen 10s of thousands of dollars from them works for the TV show.

All 3 thefts -- $4K taken from Kourtney's Hampton's rental, $50K stolen from Kourtney's Calabasas home and $250K in jewelry taken from Khloe's house -- appear to be inside jobs, with no signs of forced entry.

The 3 women say they've done everything they've been asked to do to thwart the thieves -- hiring additional security, installing more surveillance cameras and rotating staff -- all to no avail.

K K and K want producers to force the crew to take lie detector tests.
