Christie Brinkley wows 'GMA' ahead of 'Chicago' 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.
