Liza Minnelli is going to make a cameo as herself on the second season of "Smash."

The award-winning singer-actress, 66, will appear in an episode titled "The Surprise Party" that is set to air in the spring, NBC announced Tuesday.

She'll also sing an original song, written by Marc Shaiman and Scott Wittman, alongside series star Christian Borle, who won a Tony Award earlier this year for his turn in "Peter and the Starcatcher." He plays Broadway composer Tom Levitt on the show.

"Liza Minnelli is the essence of a multi-talented, singular show business sensation, particularly for her extraordinary contributions to Broadway," NBC Entertainment Chairman Robert Greenblatt said in a statement. "So what could be more fitting than to have her legendary talent on a show that celebrates a world Liza has dazzled for decades? I had the pleasure of working with Liza when we restored her landmark television special 'Liza With a Z' at Showtime, and to see her artistry up close and personal is a thing to behold."
