"The Hills" Stephanie Pratt talks about her blackouts, drug addiction, and shoplifting problem.

Looks like she has 1 or 2 or 92 vices.....

It only took a brief run-in with Lauren Conrad (and most recently Heidi Montag) on The Hills for Spencer Pratt's younger sister Stephanie to become an overnight sensation. Then came the scrutiny: A report surfaced that she had been arrested last year for shoplifting.
Stephanie, 21, details the bust, as well as her struggles with addiction, in the latest issue Us Weekly, on newsstands now.
Stephanie says she started smoking pot at 15. "In a matter of months, I was on to other things," she adds. "I was a blackout drinker too.
"Once in history class, I was so high that when the teacher wasn't looking, I asked a girl to feel my heart. It was beating so fast I thought I was going to die."
Her brother couldn't deal with her problem.
"Spencer got mad because he was always defending me at school, saying I wasn't on drugs even when I was," Stephanie says. "He stopped talking to me for a bit."
It took a 2006 arrest — she had stolen $1,300 worth of merchandise from a Neiman Marcus in Honolulu, where she was working as a production assistant on ABC's Lost — for her to realize she needed help.
"When I was arrested, I was so humiliated," she tells Us. "Because of all the drugs that were in me, I passed out and had to go to hospital, where I called my parents.
"Getting arrested was a blessing," she adds. "I don't think I would have been able to get off drugs without that wake-up call."
Now sober, Stephanie thanks her family: "They never gave up on me."
