Paris Hilton's plans to give her bare-walled prison cell a little flair fell flat when wardens at the Century Regional Detention Center in California ripped down her family photos. The socialite was unaware of jailhouse rules that forbid inmates from decorating their cells when she attempted to stick photos on the wall. Hilton's mother Kathy, who last visited Paris on Sunday, tells Fox News, "Somebody sent her some family photos and she tried to put some... on the wall and the guard came in and ripped them off." Kathy Hilton admits her daughter continues to struggle behind bars, where she's serving time for a parole violation. She adds, "She's never been alone... This is, as she calls it, a real time out." Paris is expected to be released for good behavior on June 25.
