I need help with a song I heard on the radio. .?

There was a song on the radio I heard and I don't know the name of it. I know that it had something to do with sugar. & there was a girl singing @ first and then a dude. It's NOT the song by Flo Rida. Like I said, something with sugar and the girl singin i can't wait to see you/be with you or somethin like that.
