Listen to Britney Spears on iHeartRadio

After teasing the song for a few weeks, Britney Spears has finally debuted her new song "Ooh La La" for the upcoming "Smurfs 2" movie. She called in to "On Air with Ryan Seacrest" to talk about the single, her sons, and her upcoming Vegas show.

Brit explains "Ooh La La," is a little different from what fans are normally used to hearing from her. She says, "[the song is] definitely straight-up pop … it has a young feel to it … but the the main reason why I did it was because my boys. They’re obsessed with the Smurfs. We’ve seen The Smurfs movie a million trillion times and they were told they could be in the video and all this cool stuff, so that’s the reason why I did it."
