IN DENIAL - KHLOE BLASTS RUMORS SHE'S NOT A KARDASHIAN: I'm sure by now you've noticed that KHLOE looks a little different from the other KARDASHIANS. But could it be because she has a different father???!!! That's what a report in Star magazine claims. she is not Robert Kardashian's daughter

Jan Ashley and Ellen Kardashian, two of the Robert Kardashian's ex-wives, tell the magazine the late attorney revealed to them that Khloe was fathered by another man. "Khloe is not his kid – he told me that after we got married," Jan Ashley, who married Robert after Kris, told Star.

Ellen Kardashian, who married Robert in 2003 just two months before his death, added  ... "Khloe brought it up all the time. She looked nothing like the rest. She was tall, had a different shape, light hair, curly hair." Ellen adds Robert told her that he and Kris weren't sleeping together at the time Khloe was conceived. Momma Kris, who recently admitted in her book that she cheated on Robert, called the rumors "stupid" and "silly."

Meanwhile ... Khloe went online and blasted the women, tweeting, "The audacity you have to mention my father's name like this! Should be ashamed of yourself! I let a lot of things slide but this one is really low... YOU ARE DISGUSTING! (Yes you know who YOU are.)"

IS BRUCE JENNER A CROSS DRESSER???!!!: Ellen Kardashian is also spilling a supposed secret about Kris Jenner's current husband, BRUCE JENNER.

Ellen claims that one night over drinks, Bruce's ex-wife Chrystie told her that Jenner likes to wear women's clothing!!!

Ellen claims Chrystie told her she found out upon returning from a trip. "I came back and he had gone through all my clothes.  And I found my bras… He’d clip them together and wear them.’" Bruce's ex supposedly told Ellen.

Ellen goes on the claim she was told Jenner's cross-dressing went on for years after he married Kris. Kris didn't have a problem with it, but apparently the kids didn't like it. Said Ellen, "Khloe called her dad and she was very upset, crying and screaming about it."

COULD BE TRUE, BUT PROBABLY CRAP - ARE KATY PERRY'S PARENTS TRYING TO SET HER UP WITH TIM TEBOW???!!!: "OK!" magazine claims KATY PERRY'S parents know what Katy needs to get over her breakup with RUSSELL BRAND ... some TIM TEBOW time!!!

The not-always reliable tabloid claims they've invited Tebow to speak at their church in Huntington Beach, California on a day when Katy is going to be there. And they're hoping for a HEAVENLY HOOK-UP!!!

The mag quotes a source as saying that "Katy has mentioned on more than one occasion how much she likes Tim. Katy's mom firmly believes the best cure for heartache is to quickly fall in love again. In her mind, Tebow is the perfect guy for her daughter. He's handsome, charming, intelligent and above all, a good Christian." Yeah, but would Tim Tebow date a girl who shoots cream out of her boobies? I think not. Discuss.

Meanwhile ... an absent Perry won five 'People's Choice Awards' last night, including Favorite Female Artist and Song of the Year for "E.T.". No word on why she bagged on the show after initially agreeing to appear, but everyone assumes it was because of her recent split with Brand.

WHICH ASHTON KUTCHER WOULD YOU RATHER???: ASHTON KUTCHER has said goodbye to his disheveled look. Kutcher debuted his new shorthaired, clean-shaven look yesterday while doing press for "Two and a Half Men". Which begs the question ...

Which Ashton Kutcher would you rather: Longhaired, bearded Kutcher - or - clean-shaven, shorthaired Kutcher? (And "neither" is not an option!)
