Jan. 29, 2014 — -- Christie Brinkley may be turning 60 on Feb. 2, but she doesn't look a day over 25. No, seriously, it's ridiculous.

The supermodel spoke to People magazine and said she's excited for the milestone because "I feel on top of my game."

Even though Brinkley is sexy as ever, she still thinks about her children and their feelings when she's out on the beach. Basically, she acts like a mom.

"In private I may wear a bikini, but at the public beach with my kids I would change bathing suits because they do not want to be hanging out with some old broad in a bikini," she said. ""My kids would be so embarrassed!"

Once again, Brinkley refers back to her kids - Alexa Ray Joel, 28, Jack Brinkley-Cook, 18, and Sailor Brinkley-Cook, 15 - when revealing her secret to looking so young at 60.

"Because I'm an older mom, I have a responsibility to my kids as well as myself," she says. "I want to be there for them."
