Stephanie Pratt, reality star of The Hills fame, has confessed to body image troubles which led to her problems with bulimia.

Spencer Pratt’s sister claims that her bulimia was triggered due to being surrounded by so many skinny co-stars on The Hills. She claims that producers never pressured them to lose weight but that she began binging and purging after she watched herself on-screen with Lauren Conrad, saying, “I was horrified. I remember saying, ‘I can’t believe how huge I look walking over to Lauren.’”

The full story is coming out in this week’s issue of Us Weekly.
