Every performance of Broadway's Chicago is filled with plenty of razzle dazzle, but the March 25 show had an extra special sizzle, as the revival became the fifth longest-running show in Broadway history. Christie Brinkley (who will make her Broadway debut as Roxie Hart in the musical on April 4) joined the cast and crew of the hit production to raise a glass to Chicago's incredible success. Take a look as Brinkley and current Chicago stars Leigh Zimmerman and Bianca Marroquin celebrate the amazing milestone at the Ambassador Theatre!
