Demi Moore will join husband Ashton Kutcher onstage for a 24-hour Broadway marathon next month. Kutcher was among the first movie stars to sign up for the ninth annual "24 Hour Plays on Broadway" at the American Airlines Theatre, and now the Ghost star wants in on the action.

The Hollywood couple joins Amber Tamblyn, Billy Crudup, Emily Mortimer, Emmy Rossum and newly-engaged Jennifer Esposito, among others for the benefit event, which raises cash and awareness for the Urban Arts Partnership.

The stars will collaborate on a series of plays, which are written, rehearsed and performed in 24 hours.
