Weird song, don't know where from, see if you know it?

[Jamila B]

All I know is the lyrics "Don't cha wanna wanna wanna" I'm pretty sure it's from Family Guy or the Simpsons.
Can anyone help?
Actually, I watched the video for the Fanta song, and it's not. I'm thinking it's definitely off The Simpsons. But, I don't know what episode or anything.
(I'm from Australia, and that add has never played here and I don't watch TV, so it can't be the Fanta one)
