My, my! Judy McLane, Felicia Finley, Lauren Cohn and the dancing queens (and kings) of Mamma Mia! celebrated a momentous milestone on November 9—the hit ABBA musical played its 5,000th performance on Broadway! The cast was joined by a bevy of special guests, including producer Judy Craymer, Ivana Trump, Kate Baldwin and more. After the show, the stars headed to Sardi's to chat and chow down on a Grecian disco cake created especially for the occasion by Carlo’s Bakery (of Cake Boss fame).
