GET WELL SOON, WHILE WE WATCH, OF COURSE Fleiss (Photo: Getty Images)

"If I want my Vicodin I'm going to take my Vicodin. And if I want a little of that crystal meth..." she said, trailing off a bit before throwing out a trademark zinger. "Rush Limbaugh's my idol, though. He takes 30 OxyContin a day and does that radio show," she joked. (For the record, Limbaugh claims to be clean and sober.)

For someone admitting to a potentially life-wrecking problem, Fleiss was downright jovial. She swore it wasn't the drugs talking. "My dream is to be on Celebrity Rehab ... how did I get so lucky?" she joked before switching gears and adding, "I have a substance abuse problem, and I want to deal with it. I will take it seriously." This will be her fourth stint in the tank, including two court-mandated stints and one 500-hour course while incarcerated for a 1997 tax evasion conviction. Fleiss was arrested again in February for drunk driving (the dude she was with had weed).

She tells Radar she first met Dr. Drew when he was a guest speaker at Impact Rehab Center—the toughest place Fleiss says she's been to. "There's people in there even the prisons won't take. It's really the last house on the block," she said. As for her upcoming stay for Celebrity Rehab, she only hopes her fellow cast members are big stars. "I hope there's someone interesting in there this time," she tells Radar. "The past cast made me want to get high."
