Denise RichardsYou know those celebs who deny they've been plucked...

 And tucked more times than we've had the common cold?

Denise Richards is not one of them.

In fact, she's totally frank about her trip to the placcy surgeon's.

The actress admitted on Howard Stern's radio show that she's had THREE boob jobs.

"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."

But the op left Den's boobs looking "way too big"for her body, so she went back under the knife a second time.

Is she starting to sound like Jordan, or what?

Yes she is, cos Den still wasn't comfortable with her chest, reckoning her baps were still too big.

So it was third time lucky for Den, who has settled on her boobs now.

Or has she?
