Watch Christie Brinkley is proving she can still hold her own! The 60-year-old, yes we said 60, is featured in a new in-flight instructional video for Air New Zealand wearing a super sexy white bikini! The mother of three looks hotter than ever and lucky for us, she's sharing her tips! On exercise, Christie tells People Magazine, 'I?ll run or do weights, and I do at least 10 minutes a day on my Total Gym machine. However, it?s important to have fun and mix it up! I got hooked on SoulCycle this summer and during my Christmas vacation, I did yoga.' And when it comes to her diet Christie says, 'I like to start my day with coffee and coconut milk hazelnut creamer. Then I have sheep?s milk yogurt with fruit, wheat germ and Anutra. Lunch is usually leftovers from dinner: beans, veggies.'.
