You might have heard already that Madonna is slated to perform a brand-new single during the Super Bowl half-time show. It’s called “Give Me All Your Love” and it features guest appearances by M.I.A. and Nicki Minaj. Yeah, we’re kind of interested to hear their contributions, too, and we can’t wait to see the video, which is being shot right now. And during the filming of said video, Minaj apparently celebrated her birthday — she’s 29, I think? — and someone got audio of Madonna and M.I.A. singing “Happy Birthday.” It’s pretty damn cute, if not totally silly, and you can stream it below.
