The cast of the Tony-winning revival of Chicago is being extra good to their new mama! Amy Spanger (Roxie Hart), Amra-Faye Wright (Velma Kelly) and Christine Pedi (Matron "Mama" Morton) took the time to give Williams some advice for her big Broadway debut on June 25. Spanger told the talk show queen to just be exactly who she is before she attempted Williams' signature catchphrase, "How YOU doin'?" Wright warned Williams that once she arrives at the Ambassador Theatre, she's never going to want to leave. And what did the show's current prison warden, Pedi, have to say? "All you need is big hair, big lashes, a big mouth and big boobs!" Watch the clip below, and don't forget to check out Williams do her best razzle dazzle!
