'Once Upon a Time' sneak peek of Emilie de Ravin's turn as Belle

Emilie de Ravin, best known for playing Claire on "Lost," is coming to "Once Upon a Time" this Sunday (Feb. 12). She has been cast as Belle of "Beauty and the Beast" fame. Check out this sneak peek clip of her episode.

De Ravin told Zap2it in an interview that she saves her friends and family in the ogre war by agreeing to live with Rumpelstiltskin, though over time their relationship grows into a sort-of love, though not the same romantic story as the Disney animation.

We already have a wonderful/horrible feeling that the episode is going to be excellent and also break our hearts just a little. Don't you agree, "OUAT" fans?

"Once Upon a Time" airs Sunday nights at 8 p.m. ET/PT on ABC.
