The multi-talented actress will join the cast of the show following Whoopi Goldberg’s current run in the role.

Dexter, who has appeared in numerous plays and musicals including Billy Elliot and Bad Girls, was last at the Palladium playing Nancy in Cameron Mackintosh’s 1994 production of Oliver!

The show is slated to end at the London Palladium on 30 October 2010, earlier than its original 1 January closing date. It will make way for Andrew Lloyd Webber’s big-budget new production of The Wizard of Oz. Sister Act is expected to go on to Broadway.

The part of Mother Superior was originated by Sheila Hancock in the musical, which is based on the hit movie.
