Christie Brinkley Brings Her Still-Sexy Self to GMA

Proving she's still got it, the 57-year-old struts her stuff on national TV to promote her upcoming run as Roxie Hart in Broadway musical Chicago

Seriously. Did Christie Brinkley discover the Fountain of Youth?

The 57-year-old star showed she's still got it when she stopped by Good Morning America yesterday to promote her upcoming run as Roxie Hart in the Broadway musical Chicago.

You know, the same part that a then-33-year-old Renée Zellweger took on in the 2002 movie version.

The onetime supermodel looked downright stunning in a tight, revealing red Hervé Léger number, proving that if they ever decide to remake 1983's Vacation, there'll be no need to recast the girl in the Ferrari.
