Jail-bound Paris Hilton stepped out on Monday night (07May07) to attend Sober Day, a drug awareness event organised by former O.J. Simpson lawyer Robert Shapiro - and received a little celebrity support. The socialite has been sentenced to serve 45 days in jail after violating probation for a drink driving arrest. But not everyone thinks prison is the best place for Hilton. Actor Tom Arnold, who has battled his own substance abuse problems, told reporters at the event, "I think they should send her to rehab, a real lock-down rehab and if she screws up there, then go to jail."
