Could Season 3 bring a musical episode of Ugly Betty? It's inevitable, say the cast of the ABC show. On Wednesday night at the Alzheimer's Association's 16th-annual "A Night at Sardi's" fund-raiser, almost the entire Ugly Betty ensamble - along with stars from Heroes, Boston Legal and even Brothers & Sisters' Steven Weber in a glittering snakeskin suit - performed selections from the Broadway musical Bye Bye Birdie.

Betty's Tony Plana, Ana Ortiz, Becky Newton, Mark Indelicato, Vanessa Williams, David Blue and Chris Gorham proved that they can belt out a tune like the best of Broadway, which is no surprise as most of them hail from New York and are, as Ortiz puts it, "theater geeks." For Ortiz, joining the charity show after being asked by her on-screen dad was a no-brainer. "Tony Plana's mother is afflicted with Alzheimer's, so when he asked us to do this we jumped at the chance to honor her. It's for a great cause. It's a wonderful thing." But that doesn't mean the actress wasn't nervous. "I'm shaking in my Louboutins," she laughed. - Carita Rizzo
