Christie Brinkley worked it for fans at the "Good Morning America" studios in New York this morning.

The 56-year-old model posed for photographers, removing her trenchcoat to reveal a tight red dress dress. Yowza! We could only dream about looking that good at her age. She also teased her fans with one of her stiletto heels.

The model was appearing on the morning talk show to promote her Broadway debut as Roxie in the musical "Chicago."
