Nicole Richie reportedly fainted during a shopping trip on Saturday. The reality TV star, 24, was browsing through the clothes at Los Angeles boutique Kitson when she fell to the floor, according to magazine Life & Style.

An onlooker says, "She was looking through a rack of clothes when she suddenly fainted and hit the floor. The staff helped her to a chair and offered her something to eat. She shot back, 'No!' and mumbled something about it being 'so hot.'"

Earlier this year, Richie was forced to deny reports she has an eating disorder, but admitted, "I know I'm too thin right now, so I wouldn't want any young girl looking at me and saying, 'That's what I want to look like.' I'm not happy with the way I look right now."
