brinkley red Christie Brinkley wows 'GMA' ahead of 'Chicago' debutChristie Brinkley, we must remember, is a supermodel. That’s a designation that never goes away. So we shouldn’t be too surprised that the 57-year-old turned heads in a skin tight red Herve Leger dress when she stopped by “Good Morning America” on Wednesday (April 6) to talk about her upcoming Broadway debut.

Brinkley will join a long line of women — from Bebe Neuwirth to Kelly Osbourne — to guest star in the musical. Brinkley’s 11-week engagement kicks off Friday (April 8) at New York’s Ambassador Theater.

The model admits she did get a bit of advice from ex-husband Billy Joel about how to project her voice without losing it.
