Stephanie Pratt, perhaps best known for her role on MTV's low-key great The Hills, recently revealed a teenage crystal meth addiction. In her new memoir Made In Reality: From the Hills of L.A. to London's Made in Chelsea, Pratt says she started smoking meth when she was "14 or 15," adding that addiction "developed instantly."

Eventually, says Pratt, she was smoking as much as "12 or 13 times" a day:

“I would wake up, and pop out of bed because I was so excited to take my meth. I’d go into my bathroom and smoke, immediately, then brush my teeth, put on my makeup and get dressed. Then I would get in my car; I would be at a red light and during that pause I would bend down and smoke it in the driver’s seat at the wheel.”

Pratt cites her rock bottom moment of revelation as a near overdose on OxyContin, cocaineXanbars, and whisky. "I woke up and I was in UCLA Medical Center," remembers Pratt. "I didn't care about anything. I could live or die. I didn't care."

Though she doesn't reveal whether the addiction carried on through the filming of The Hills, which ran from 2006 to 2010, she does reveal that her struggles (including an eating disorder) are now under control.
