Can you believe she's 60!?

Christie Brinkley showed off her incredible figure -- and some major cleavage -- at a Sports Illustrated Swimsuit Edition 50th Anniversary Pink Carpet party on Monday night in New York City.

The sexy supermodel was nothing short of stunning in a low-cut orange dress with her hair in voluminous curls as she posed for photographers on the pink carpet.

She was there to celebrate another blonde beauty -- Barbie! The iconic doll is featured inside this year's highly-anticipated issue.

So, how does Christie maintain that enviable bod?

"I love hanging out in health food stores," Brinkley recently told People magazine. "Some people are gourmands who love a fish smothered in cream. That doesn't appeal to me. I treat every day like I'm eating to fuel my body."

Christie also stays extremely active -- running, cycling and yoga are just a few of her hobbies. She also tries to get in a work out even when she's doing normal tasks around the house, like "[doing] leg lifts when brushing my teeth," she confessed.

We think she looks better than most women half her age!
