Once Upon a Time is all new tonight with an episode that puts a twist on the classic tale of Beauty and the Beast.  LOST's Emilie de Ravin will be appearing as Belle, who agrees to go live with Rumplestiltskin (a.k.a. "The Beast") in order to save her town.  Watch Emilie as Belle and Rumple as the Beast in two sneak peeks here.

Meanwhile, in Storybrooke, Mr. Gold is also playing a big role in tonight's episode of Once Upon a Time.  He comes home to discover that his house had been robbed.  Worried that he may use this opportunity to engage in a bit of vigilante justice, Emma decides to keep an eye on him.

Storybrooke is also celebrating Valentine's Day and Mary Margaret decides to use the holiday as a chance for a girls' night out with Ashley and Ruby.  Ashley's surfacing for the first time since her early appearance while pregnant and she's using the night as a chance to let loose after being cooped up with her new baby for so long.  She's also pretty upset about her boyfriend working all the time, but from the looks of these photos, it appears that he may have a nice surprise for her for Valentine's Day.  As for Mary Margaret, she seems to have come to the realization that her "relationship" with David is not exactly ideal.  Will he be able to make a move soon and leave his wife to be with her?

Watch three sneak peeks below for tonight's new Once Upon a Time, airing at 8:00 p.m. EST on ABC.  You can also view a promo here and photos of Beauty and the "Beast" here.
