We're not sure why it took this long, but it looks like porn vixen Farrah Abraham is about to take on a new role -- in the bedroom of Charlie Sheen.

The always-bashful Farrah wouldn't come right out and name Sheen directly, but she gave In Touch a little hint about the identity of the celeb she says she's been chatting with. She says, “I think if I gave you some clues, you would guess it. He has been married, lives in L.A., and he basically was like the main character of a show, then left and they replaced him with Ashton Kutcher."

She should call up the C.I.A. -- they need people who can keep secrets!

Kanye says he is not cheating on his pregnant girlfriend Kim Kardashian -- and that the woman who says so just wants some free press.

As we reported, 24-year-old Leyla Ghobadi told Star magazine that she met Kanye at one of his concerts in July 2012 -- three months after Kim and Kanye began dating -- and hooked up a couple of times, once after Kim got pregnant. Leyla says Kanye confessed that the relationship was a publicity stunt.

But Ye's reps tell TMZ, "This is a sad attempt to hurt two people trying to live their lives.This most recent attack on Kanye West and his family is totally without merit. It's a blatant attempt by a misguided individual who is clearly seeking publicity, and another in a series of malicious stories drummed up by non-credible 'news' sources."
