Watch Chicago's Christie Brinkley Razzle Dazzle Jay Leno on The Tonight Show

Christie Brinkley, the golden-tressed former supermodel, is about to star in the Tony-winning revival of Chicago. Before hopping a plane to start rehearsals for her role as Roxie Hart, Brinkley swung by Jay Leno's couch on The Tonight Show. Brinkley chatted about her memorable appearance as "the girl in the red Ferrari" opposite Chevy Chase in the 1983 hit flick National Lampoon's Vacation before talking up her Broadway debut. Watch Brinkley charm Leno below and then see her at the Ambassador Theatre beginning on April 4.
