The Kardashians

A group of pranksters is on a diabolical mission to destroy the Kardashian family -- planting fake stories in the media, spreading nasty rumors, even making fake restaurant reservations -- at least ... Kris Jenner thinks so.

Sources close to Kris tell us, the matriarch is convinced she and the rest of the Kardashian family are the victims in an elaborate prank plot -- and she believes the people behind it are the same people who spread rumors she was in a sex tape.

We're told the group is responsible for a string of pranks against the family -- planting bogus stories about the sex tape, Kris dating a rapper, Kim's wedding, Rob Kardashian in rehab, and more.

Even crazier ... Kris believes one of the pranksters has been impersonating her to a tee, booking fake photoshoots and fancy restaurant reservations around the country.

We're told the group booked a Kardashian reservation at every Nobu in America last week -- and Kris only found out when her phone rang off the hook with requests to confirm. We're told Kris has now given her favorite restaurants code words to verify Kardashian reservations from here out.

Just when you thought the Kardashians couldn't get any faker.

Kris Jenner has a medical problem that required her to go to the hospital, and even though they're separated when times get tough her go-to person is still Bruce.

We've learned Kris just went to a hospital in Thousand Oaks -- near her home -- for X-rays and possible tests for an undisclosed medical problem. She was accompanied by Bruce, who we believe came from his home in Malibu to be with her.

Kris and Bruce have actually become closer we're told since their separation, because there's no tension over the relationship anymore -- they're simply close friends and confidantes.

Again ... it's unclear why Kris needed to go the hospital.

Kris Jenner's taking no chances after Kim Kardashian came face-to-face with a stinky stalker outside the Jenner home last month -- Kris has now hired 24/7 security.

Kardashian sources tell TMZ, guards are parked outside the family home in 2 vehicles which monitor her Hidden Hills estate 24 hours a day -- and the guards are ARMED.

We're told she's paying several thousand bucks a month for the hired muscle.

Kris has had her share of scares over the last year -- threatening phone calls, paparazzi intruders, SWAT pranks -- but the stinker was the last straw.

It seems French Montana is banging Khloe Kardashian ... and his main squeeze Trina is hotter than fish grease over it -- and the rapper's now telling friends she's done with his tricky ass.

Trina and French weren't officially BF and GF -- but we're told they were living together in New Jersey -- sources close to the couple say she was devastated after seeing video of Khloe/Montana all over each other last week at a strip club.

We're told Trina feels like she got played -- She and French were talking regularly up until a few weeks ago when he started working in L.A. on his next album ... and now it's radio silence.

Khloe Kardashian and French Montana are going through a lot of effort to try and and show people they aren't banging ... which TOTALLY means they are.

KK and FM hit up Hooray Henry's in West Hollywood Wednesday night, but took ridiculous steps to exit separately. First it was Khloe, blowing off our photog's questions and heading into her SUV.

Then, as if he was waiting for the precise moment when Khloe got inside her car, French emerged from the club -- skirting our questions as he walked to his car ... where Scott Disick was dutifully waiting inside.

Funny side note ... watch as Scott yells at French when French tries to get in the driver's seat. You can barely see Scott behind French's MASSIVE bodyguards.

As TMZ first reported, the pair spent last weekend together -- Khloe helped French look for houses in LA, before the pair spent Saturday night at a strip club in Phoenix.

Khloe Kardashian and rapper French Montana have been spending a lot of time together ... the kind of time that leads people to ask, "Are they banging?"

We're told French is on the hunt for a new pad and took Khloe along to check one out -- a 4,800 sq. ft. Hollywood Hills home that rents for $29,000/month. It's a 4 bedroom, 4 bath house with a wine and cigar cellar, a sauna, and screening room.

And, they hit up Pink Rhino in Phoenix this weekend where French was a promoted guest. We're told the pair and their entourage went through 10 bottles (on the house, of course) and shelled out $7K on girls.

Bruce and Kris Jenner may still be wearing their wedding rings ... and occasionally even be touchy feely ... but they are NOT back together.

Kardashian family sources are scoffing at reports the couple rekindled things in Thailand.

We're told they don't hate each other. It's actually the opposite ... they're still close.

That said ... they are leading very separate lives. As we previously reported Bruce has had it with Hollywood and is living alone in Malibu. Kris is cranking out more shows at her home base in Calabasas.

As for Bruce's comment at LAX Wednesday -- insinuating they were never separated -- well, everyone tells a little white lie occasionally.

As for both of them wearing their rings again after a hiatus ... they both consider them "friendship rings."

They've been living apart for months, but Bruce and Kris Jenner claim to be reunited -- which can only mean they had one helluva vaca in Thailand.

Bangkok -- saving marriages since ... well, never.

Bruce and Kris Jenner may have decided to consciously re-couple, because they not only held hands together as they arrived back in the U.S. ... Bruce seemed to say they were never apart.

Kris and Bruce were at LAX, returning from Thailand, when one of the photogs asked if they were together again. Listen closely ... he says, "We've been together."

And ... it looks like both are wearing their wedding rings.

Here's the problem ... Kris herself said publicly last October they had separated, and Bruce moved out of the family home and put down stakes in Malibu.

Bangkok really changed Bruce Jenner -- he returned to L.A. holding hands with his estranged wife today.

Kris Jenner was grinning for cameras as she and Bruce walked out of LAX with a tight grip on each other -- which seems odd for a bunch of reasons ... not the least of which being the fact they separated back in October.

Then again ... they're coming back from a Kardashian family trip to Thailand for their TV show -- so, as always ... hard to tell what's real and what's just for cameras.

Maybe Bruce just talked Thai real well.

Khloe Kardashian's all bent over Ray J's penis and the fact it dared to star in a Kim K. sex tape spoof with Joan Rivers -- and now KK's getting revenge ... by pulling out on Joan.

Insert penis-vagina joke here.

Kris Jenner has been bombarded by someone who is claiming to have a sex tape starring Kris herself and they will release it UNLESS she pays a Queen's ransom ... and now cops are on the case.

Law enforcement sources tell TMZ ... L.A. County Sheriff's Deputies went to the Jenner house Tuesday and took a report, which says Kris has been receiving up to 300 phone calls, voice mails and texts a day for the last few weeks -- day and night -- from someone who says they have the tape.

We're told the person has recently told Kris if she doesn't ante up a big sum ... TMZ will post the sex tape. FYI ... it's not true and besides, it's not up our alley.

Kris told deputies there is no such tape and the caller even flip-flopped during several calls and said Khloe -- not Kris -- starred in the tape.

Khloe Kardashian is steaming mad at Joan Rivers for spoofing her sister's sex tape by doing a pretty hilarious rendition with Ray J ... so she bailed on co-hosting Joan's show at the last minute.

Khloe was scheduled to shoot Wednesday for Joan's E! show "Fashion Police," but sources close to production tell us ... Khloe pulled out .... hmmm, just like Ray J.

It's thrown Joan's show into panic mode -- probably to the satisfaction of Khloe -- because they have to scramble for a new co-host and re-do the script.

TMZ broke the story ... Joan filmed a comedy sketch with Ray J for her new WE tv show "Joan & Melissa: Joan Knows Best?" -- spoofing Ray J and Kim Kardashian's famous sex romp.

It's pretty hilarious ... but the Kardashians aren't laughing.

Kanye West was in his danger zone last night (LAX) .... surrounded by his greatest anger trigger (paparazzi) … but he went through without incident.

Ye and Kim Kardashian arrived at the airport and were met by a slew of paps. First, our guy asked if the couple had seen Seth Rogen's parody Vogue cover. A bunch of other questions were hurled, but Kanye stayed cool.

He really doesn't have an option. He's on probation in the LAX assault case and ordered to undergo anger management therapy.

But something else happened. Some random people screamed out his music sucks, and "make me rich!" Maybe they knew ... Kanye paid one of his assault victim's more than $250K for a smack to the face, so he established a going rate.

Reza Farahan from "Shahs of Sunset" just made Kanye West's list -- that's what happens when you say Kim Kardashian would NEVER make it on the cover of Vogue ... unless Kanye bought it for her.

We asked Reza about Kim and Kanye's new cover shot for the fashion bible ... and he's not convinced Kim deserves the honor, to say the least -- "That's a legit fashion magazine, and this bitch was selling her s*** at Sears."

You gotta watch ... Reza tries to soften his shot -- at Sears and Kim -- but fails. Also, he's got a great idea for the next Vogue cover.

Scott Disick threw caution to the wind and gave Jon Hamm a run for his free-flowing money as he went out on a grocery run yesterday in Calabasas.
