nullBusy Keke Palmer, who next stars in Fox’s horror comedy series "Scream Queens," has joined the cast of the network’s live staging of Grease, BuzzFeed reports.

Palmer will play Marty Maraschino, a character that was originally played by Dinah Manoff in the 1978 movie.

Palmer joins the previously-cast Julianne Hough and Vanessa Hudgens (who will headline the musical as Sandy and Rizzo, respectively).

The 3-hour "Grease" live event airs Sunday, Jan. 31, 2016 at 7/6c. It’ll follow NBC’s live musical staging of "The Wiz" this Christmas.
