Victoria's Secret May/June Song

There's a song that plays there that I don't know the name of and gets stuck in my head. A female sings the entire song and it has a very summer pop beat. (and no, it's not call me maybe)

The chorus line is pretty distinctive, its something like: la la la la la la la laaaaa, la la la la la la laaaa, pitching up and down through.

Any help would be appreciated.

is it "want u back" by cher lloyd.?
