Paulina PoriskovaIf there's one thing Paulina Porizkova learned from her experience as a model, it's that being beautiful can get awfully ugly.

So says the '80s cover girl in a scathing new interview in which she groans about growing older, slams her fellow supermodels and disses celebrities with bad plastic surgery.

"Nothing ages as poorly as a beautiful woman's ego," the 45-year-old Czech tells the New York Post. "When you have used your beauty to get around, it's like having extra cash in your back pocket.

"I was so used to walking down the street and having the young guys passing by at least give me a flicker of a look. But once you're over 40, you become invisible. You're a brick in the building and it's sad. It just feels like the sun went down a little bit. It got a little cloudy outside."

Once one of the industry's most in-demand models, the former Sports Illustrated cover girl went on to enjoy a brief film career, starring opposite Tom Selleck in 1989's 'Her Alibi.' But these days, Porizkova claims the job offers are few and far between.
