A peeved Khloe Kardashian reportedly bailed on co-hosting “Fashion Police” after Joan Rivers spoofed sister Kim’s sex tape on her reality show.

TMZ says producers of “Fashion Police” which regularly features Kelly Osbourne and Giuliana Rancic, are scrambling to find a new co-host after Khloe’s last-minute withdrawal.

Khloe was due to shoot the show today, but TMZ says she was “steaming mad” at the spoof on “Joan & Melissa: Joan Knows Best?” in which Ray J — Kim’s ex-boyfriend — is holding a video camera while in bed.

The clip features the couple getting cozy under the duvet, while Ray J tells 80-year-old Joan: “You’re the best. You’re twice the woman Kim was.”

“No, she was 22 at the time, I’m three times the woman,” she says, adding, “Be gentle. I don’t want to break a hip.”
