The song is for The Smurfs 2 movie soundtrack. The singer's two children appeared in the video. The video starts with the family taking in a film at their local cinema. All is well until Spears is magically zapped onto the screen where she, after recovering from the shock, performs 'Oo La La' with the help of some ankle high Smurfs. 

The 31-year-old wears a cherry red dress and leopard print shoes with red wedge heels. She makes a bizarre addition to the video which features pop-up book illustrations, film footage and the miniature blue Smurfs. This does link with the film which consists of both animated characters interacting with non-animated actors and locations.

Spears' two sons, Sean and Jayden, seem truly uncomfortable in the limelight. At one point in the video, Spears appears flanked with her children who stand somewhat awkwardly and avoid looking at the camera.
