Disney’s newest girl-centric comedy, “Princess Protection Program,” debuts tonight and we’re wondering, are you going to watch? It’s a royalty-meets-reality, fish-out-of-water, Princess Diaries-type romp about a coup-threatened princess who takes refuge in the covert Princess Protection Program. Now she’s masquerading as an average 16-year-old visiting her American tomboy cousin. Princess Rosalinda is played by young singer-actress Demi Lovato of “Camp Rock” fame, and her country cousin is teen pop star and Mouseketeer Selena Gomez of Disney’s “Wizards of Waverly Place” and a million fan mags. We’ve posted the trailer after the jump. But first!
