Paris Hilton to pose for Playboy

Paris Hilton has been invited to pose for Playboy, but her mother won't agree.

Playboy millionaire Hugh Hefner, who would love the hotel heiress to pose for the magazine when she is released from jail, feels Kathy's disapproval will prevent her.

Hefner told Access Hollywood: "Well, that's a standing offer. I think the problem quite frankly is mama. Mama doesn't want her to pose."

Meanwhile, the 26-year-old has been spending her time behind bars reading fan mail.

The Simple Life star has even been replying to the letters that touch her most.
