Sharon Stone "wanted to die" when she put on weight in her 20s.
The 55-year-old actress gained 45lbs as a side effect from medication she was given after an accident and admitted she hated the attention her newly-curvaceous figure received from men.
She said: "When I was 20, after my horseback-riding accident, I was given cortisone shots and I gained a lot of weight from that, like 45 pounds.
"I looked a little like Anna Nicole Smith, with a tiny waist, big boobs, and a big butt. Everywhere I went, men went insane over my va-va-voom body. I just wanted to die and I became an introvert."
The 'Alpha Dog' actress - who has three adopted sons, Roan, 13, Laird, eight, and Quinn, seven - also admitted she has struggled with getting older and has "cried and cried" over the way she has changed with time.
She told the new edition of Shape magazine: "There was a point in my 40s when I went into the bathroom with a bottle of wine, locked the door, and said, 'I'm not coming out until I can totally accept the way I look right now.'
"I examined my face in the magnifying mirror, and I looked at my body, and I cried and cried and cried . . . I thought, 'I'd like to age like a dancer.' I want to keep my body in shape like that."
