What song goes whoa oh oh oh oh oohh ohhhh?

I was in hollister and I heard this song. A guy sings some parts of the song then a girl follows. I've been looking up what song this is but a lot of people have answered Zombie Nation or Poker face.Not, Unfortunately those artists are not what I am looking for
I heard it twice in the mall. this is all that I remember. The girl part has a soft mellow voice.
