Actress Brooke Shields is nursing a broken hand after injuring herself while preparing to star in a new play.

The Blue Lagoon star has been sporting a cast over her wrist and last two fingers after slipping while rehearsing for her part in an upcoming Los Angeles stage show.

Shields' spokesperson tells People.com, "Brooke broke her hand during rehearsal for the musical Leap of Faith. The cast will be off before previews on September 11. It was a minor break and did not affect the production schedule."

Opening night for the production, an adaptation of Steve Martin's movie Leap Of Faith, is scheduled to take place on Oct. 3, 2010 at the Ahmanson Theatre.
