Charlie Sheen - Hotel Boss Comes Clean About Stars' Dirty Secrets

Hollywood stars are running for cover after a bitter former hotel security boss has decided to breach her confidentiality agreement and reveal all about the celebrities' dirty secrets.

ELOISE MOHSIN worked at the exclusive Phoenix Ritz-Carlton hotel in Arizona from 1999 to 2002, when she left amid a sexual harassment scandal.

And now she's coming clean about stars like BRITNEY SPEARS, TYRA BANKS and GWYNETH PALTROW to get back at her former employers for not supporting her harassment claims.

Mohsin tells America's NATIONAL ENQUIRER, "I am speaking out because I have nothing to lose."

She claims Paltrow once spent the night with pal SHERYL CROW at the hotel: "Paltrow arrived under an assumed name and spent the night in Crow's room."

Mohsin also alleges that supermodel TYRA BANKS tried to romance SEAN 'P DIDDY' COMBS when the pair were both guests at the hotel - by sending flowers and intimate notes to his room.

But the most shocking revelation in Mohsin's Enquirer tell-all is a claim that a maid once found a used pregnancy kit in JUSTIN TIMBERLAKE's room after Britney Spears spent a night with her then-boyfriend.

She says, "The (room service) server reported seeing Britney inside (the room) wearing a silky negligee."
