Kristen Bell Does "Bye Bye Birdie"

Kristen Bell was among those gathered at the Beverly Hilton Hotel on Wednesday night for the 16th annual Alzheimer's Association "A Night at Sardi's" benefit.

For the occasion, in which Boston Legal creator David E. Kelley was honored for his portrayal of Alzheimer's disease on the show, the 27-year-old actress lent her singing voice to a celebrity-filled version of Bye Bye Birdie.

The show was directed by Seinfeld alum Jason Alexander and according to USA Today reports, "The hotel's ballroom was transformed to look like the famed New York restaurant for which the event is named."

Joining the Heroes hottie in the Birdie production were performers such as Vanessa Williams, Lea Thompson, Ana Ortiz, Zachary Quinto, and Zachary Levi.
