TV darling Emilie de Ravin gets to play a Disney princess, on ABC's "Once Upon a Time."

The "Lost" star has just been cast as the infamous beast-lover, Belle, on this new ABC drama. Her debut would be in spring 2012, and only an episode at that.

Details on the 29-year-old's appearance are still being kept under wraps. However, it is certain that we are to expect the presence of hairy Gaston, who has a mysterious connection to the scheming Rumplestiltskin, played by Robert Carlyle.

De Ravin's previous TV credit was playing single mom, Claire Littleton, on "Lost." Coincidentally, creators of the said hit series, Adam Horowitz and Edward Kitsis, are also the ones responsible for "Once Upon a Time," making it a reunion for her with them.

The blonde beauty has also been seen in a couple of flicks, including the neo-noir "Brick" with Joseph Gordon-Levitt, "The Hills Have Eyes" and last year's "Remember Me," where she was paired with heartthrob Robert Pattinson.

Aside from De Ravin, another form the "Lost" cast, Alan Dale, will also appear. He is set to play the role of Snow White's father, King Leopold, on the series.

For those who don't know what the show is about, it's basically a fairy tale-adapted drama. It centers around Emma Swan, a bail bonds collector whose life goes off the rail after she finds her lost son, Henry.

He then takes her to Storybrooke, a town whose inhabitants he perceives as characters from fairy tales, including Snow White and Prince Charming, who are said to be Emma's parents.

The freshman series is an ensemble one, featuring movie actress Ginnifer Goodwin, Lana Parilla and Josh Dallas. Newcomers Jennifer Morrison and Jared S. Gilmore play the mother-and-son lead.

"Once Upon a Time" has enjoyed immense success since its premiere in October. Its pilot episode pulled in 12.8 million viewers alone, equalling other ABC favorites such as "Modern Family," "V," "Cougar Town" and "FlashForward."

Recently, it also has been given a full season order, alongside the Tim Allen comeback "Last Man Standing."

Fairy tale dreams do come true, at least for the production studios.
