Friday night, stars like Olympian Aly Raisman, model Chrissy Teigen and Christie Brinkley walked the red carpet.

Brinkley is posing in the magazine at 63.

Her secret? "A good attitude," Brinkley said.

"You can be the most perfect picture, but if you're grumpy, if you have a negative attitude, that's what's going to show through."
