If you're wondering whether to sit through 'Smurfs 2' with or without (no judgement) the little ones, perhaps this will sway your decision -- Britney Spears, the trainwreck only rivaled by Lindsay Lohan and Amanda Bynes, is contributing a new song to the official soundtrack that will be "Smurftastic."

Yes, folks, that was her phrasing: "I have always loved the Smurfs as a kid and now my boys are the biggest Smurfs fans EVER. I wanted to surprise them with a song in the movie. I know they'll think it's Smurftastic!" You may commence with the pretend puking now.

As per the Wall Street Journal, her new song will be titled "Ooh La La" (though we might be saying anything but) and will play over the end credits of 'Smurfs 2.' As director Raja Gosnell says, "'Ooh La La' is the perfect Smurf-party song, and the perfect button on the film for audiences around the world."

From the official 'Smurfs 2' synopsis:

The evil wizard Gargamel creates a couple of mischievous Smurf-like creatures called the Naughties that he hopes will let him harness the all-powerful, magical Smurf-essence. But when he discovers that only a real Smurf can give him what he wants, and only a secret spell that Smurfette knows can turn the Naughties into real Smurfs, Gargamel kidnaps Smurfette and brings her to Paris, where he has been winning the adoration of millions as the world's greatest sorcerer.

Neil Patrick Harris, Jayma Mays, Sofia Vergara, Katy Perry as Smurfette and Hank Azaria as Gargamel are just some of the players returning from the first film, while newbie Brendan Gleeson also joins the cast. 'Smurfs 2' hits theaters on July 31, 2013, so we still have some time before we have to hear Britney's "Smurftastic" (yes, we still can't get over the fact that she used that word) "Ooh La La." But who knows, maybe we're just being pessimists.
