Denise Richards has revealed that she is currently on her fourth set of breasts - but wishes she'd kept her natural curves.

The actress-turned-reality TV star underwent her first breast enlargement operation as a teenager, and later received another surgical boost but was unhappy with the over-inflated results.

Her third operation was a breast reduction.

She told US DJ Howard Stern: "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."

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

In a separate interview Denise – who is divorced from actor Charlie Sheen, with whom she has two daughters, Sam, five and Lola Rose, four - said she had her implants reduced after playing a Bond girl in The World Is Not Enough.

She said: “They looked ridiculous on my frame. After I did the Bond film, I had them changed out and made smaller.”

The 38-year-old actress now believes she made a mistake and would dissuade any young girls from having surgery.

She said: “It was a stupid thing to do when I was a teenager. I would encourage anyone that young to not do it because you don’t realise the complications, the things that can go wrong as they did with me.”

Have they or haven't they?
