Wow. And we thought Tara Reid had an ugly history of boob jobs...

Appearing this week on Howard Stern's Sirius Radio show, Denise Richards admitted that said she got breast enhancement surgery "a long time ago" after moving to Los Angeles to be an actress.

"I was 19, and my roommate had the best boobs ever, and she had just had hers done," the exploitive mother said. "I was flat as a board, and I thought 'Whoa, you can just buy them' and stupidly had them done!"

It didn't go very well. Following her first operation, Richards said her boobs looked "way too big for my body."

So she got more work done on them.

"The next guy put bigger ones in, and it was not good - they were a D!" she said, adding that a third procedure finally fixed the problem.

Would Richards advise any young actresses to get their chests worked on? No.

"I was young and should have researched better. You know, it was a big mistake. Young girls, don't do it!"
