Third time's a charm for Denise Richards' breasts? Hey, it's complicated

Howard Stern asked Denise Richards, 38, the unthinkable on his Sirius Satellite Radio show Thursday.

Are her breasts real?

"Um, natural on outside, on the inside they are not," she confessed, explaining that she got the surgery "a long time ago" when she was a young and struggling actress.

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

Afterward, she says, her breasts looked "way too big for my body."

So she had a second operation. But apparently, she forgot to tell the doctor to put in smaller ones.

"The next guy put bigger ones in, and it was not good -- they were a D!" she said

Thankfully, the third time was a charm.

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