Britney Spears joins the Smurfs family with "Ohh La La," a song that will be featured on "The Smurfs 2" soundtrack and play during the end credits of the film sequel, due July 31.

"I have always loved the Smurfs as a kid and now my boys are the biggest Smurfs fans ever," Spears says in a press statement. "I wanted to surprise them with a song in the movie. I know they'll think it's Smurftastic!"

Britney is in good pop diva company alongside Katy Perry, who will reprise her role as Smurfette. The followup to the 2011 Sony Pictures animated hit centers around a plot by the little blue characters to save their beloved Smurfette from "the Naughties," a clan of mini Smurf wannabes created by the evil Gargamel. 

Also returning for the sequel are Neil Patrick Harris, Jonathan Winters, and Sofia Vergara. Christina Ricci debuts in the franchise as Vexy, one of the Naughties.
