'Once Upon a Time' casts Emilie De Ravin as Belle

"Once Upon a Time" has already introduced Snow White. Cinderella is making her first appearance this Sunday (Nov. 13). And now Belle has been cast for an upcoming episode, ABC confirms to Zap2it.

As first reported TV Guide, "Lost" alumna Emilie de Ravin has been cast as the "Beauty and the Beast" princess. There are few details available yet for her episode and role, other than she will have some dealings with Rumpelstiltskin, but her would-be suitor Gaston is also appearing.

This is the second "Lost" alum to schedule an appearance on "Once Upon a Time." Alan Dale, "Lost's" Charles Widmore, has been cast as Prince Charming's father.
