Christie Brinkley Still Sizzles at Sixty at Sport Illustrated Swimsuit Bash by Barbie

Christie Brinkley arrived at the Sports Illustrated Swimsuit Barbie bash in a form-fitting black dress revealing the supermodel is still sexy at sixty.

Christie Brinkley lit up the Barbie Celebrates The 50th Anniversary Of Sports Illustrated Swimsuit party last night as she put most models to shame.

Christie Brinkley turned 60 on Feb. 2. That hasn't topped Christie from modeling and it hasn't stopped people from wanting to see Brinkley posing in a swimsuit.

Just last month, Brinkley was smoking hot on the new cover of People magazine.

The cover of People shows Christie Brinkley in a tight revealing swimsuit. The February cover of People magazine is reminiscent of Christie Brinkley's first Sports Illustrated's swimsuit issue cover. Sports Illustrated is a sister publication of People magazine.

The supermodel who used to be married to Billy Joel told the magazine she dates younger men.

Christie also told the gloss mag that "It seems like during this period that most of the guys are like 38, 39, 42, like that sort of age group. It's funny because I think that at that age they have nothing to prove. They're very confident and do they just what they want to do." [With] men my age I feel quite invisible to them."

Brinkley said "I think a ten year span is fine."

But at sixty, Brinkley draws a new line. She may pose in a swimsuit, but her bikini days are behind her. Christie said "My kids would be so embarrassed. 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."

MJ Day, senior editor for Sports Illustrated's swimsuit issue says it is too soon for Christie to put her bikini away. He says "She looks phenomenal. She has the legs of a 30-year-old and the face of an angel. She's what you aspire to look like at 60. She's mind-blowingly beautiful."

Brinkley has been divorced four times, including a very public and nasty separation from architect Peter Cook in 2008.

How does she stay in Bikini-Ready Shape? Brinkley says she has to stay young for her three kids, musician Alexa Ray Joel, 28, college freshman Jack Brinkley-Cook, 18, and up-and-coming model Sailor Brinkley-Cook, 15. She says "Because I'm an older mom, I have a responsibility to my kids as well as myself. I want to be there for them."

Brinkley has never had plastic surgery, she has been a vegetarian since she was 13.
