Stephanie Pratt says appearing with super skinny friends like Lauren Conrad on "The Hills" made her hate her body and turn bulimic, according to Us Weekly.

The 23-year-old began binging and purging in 2007. She says, "I was horrified. I remember saying, 'I can't believe how huge I look walking over to Lauren.'"

Once, when filming in Hawaii in bikinis, the size 0-2 Pratt asked co-star Audrina Patridge, "What looks better, 'shirt on or off?'" Patridge said 'On.'"

Pratt insists producers never pushed her to lose weight. However, she said, "It's embarrassing working with skinny girls."

Perhaps she needs friends like Kim Kardashian instead?
