Ah, the naïveté of youth. Actress Denise Richards came clean about her surgical enhancements on Howard Stern's show today (a popular place for confessions) admitting that she has had three breast implant operations. The first came just as the rising star moved to Los Angeles when she was only 19 years-old. "I thought, 'Whoa you can just buy them' and stupidly had them done!" Richards said. Despite the first set looking too big, Richards went for another upgrade, which she quickly deemed over the top. So, with the third procedure, they were just right. "You know, it was a big mistake. Young girls, don't do it!" Richards said on the air.
