Singer-songwriter Bonnie McKee has revealed that 'Ooh La La', which Britney Spears recorded for the 'Smurfs 2' soundtrack, was intended to be a super sexy song and she had to tweak it considerably for the movie.

Speaking to MTV News about the cut, McKee explained that she didn't work on it for the film originally although when it was confirmed that it would appear in the motion picture she had to change it to make sure it was child-friendly:

"I actually came in and was the doctor behind it. A lot of it was already written. It was a great song to begin with. ... They wanted it for the 'Smurfs' movie, and it was originally pretty sexy. I was like, 'OK, how do I take this sex-drenched song and make it Smurfs friendly?'"

"That was kind of my task, but it still had to work at radio and be something that people would buy as a Britney Spears song because she's not a Smurf. So, it was just kind of fun to find double entendres to put in there and kind of trick the parents into thinking it's kid friendly."
