Britney Spears debuted her new song “Ooh La La” on Ryan Seacrest’s radio show Monday, which will appear on the soundtrack to the film Smurfs 2 and will play over the closing credits when the movie comes out on July 31.

The song was co-produced by Lukasz "Dr. Luke" Gottwald, Ammo and Cirkut, who also worked on Femme Fatale.

Spears announced the song in April, saying “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!”

She also teased, “Remember that surprise song I recorded for my boys? It's coming soon! #OohLaLa for #TheSmurfs2 🙂 Stay tuned for more...” The song was leaked about a month ago, but she officially debuted it on Monday.

Billboard reports Spears told Seacrest about her upcoming album, which she’s working on with will.i.am.

"I want to definitely take this album and have a new approach with it and make it a little different than anything I've ever done," she said. "Will has a lot of really interesting different tracks that I've listened to that are really cool that I haven't actually written on yet, but there's a lot of guitar and I think people will be surprised with this album. It's gong to be really different."
