The 32-year-old busty blonde has embraced her curves in recent years but the pin-up confesses she wasn't always proud of her figure and trademark derriere.
She tells Sister 2 Sister, "When I was 18, the J. Lo (Jennifer Lopez) butt was not in. To have a booty was not the thing. You were considered fat if you had a booty... I was being cast in stuff where you'll see all these really beanpole-looking white girls with blond hair and big boobs. That's what I wanted to be... I was pulled aside during a Playboy photoshoot and a director told me that I needed to lose weight - that I was getting fat...
"When I heard that, I went into full craziness. I went and tried everything from diet pills to cleansing to everything you could possibly do to get rid of your butt. Bulimia - I tried that but I love my food too much."
And Austin credits Ice-T with helping her learn to appreciate her assets.
The hip-hop star adds, "I told her, 'You got a little waist and a nice, round butt.' I said, 'That's what's unique about you. The boobs - anybody can go buy them.'"
