Pink and Sia are two artists with incredible voices and stage presence, and their new collaboration "Waterfall" is the duet we didn't know we needed in our lives. It's an up-tempo jam that also serves as the debut credited single for Norwegian production duo Stargate, who have crafted multiple hits for Rihanna including "What's My Name," "Don't Stop the Music," and "S&M." While Sia has written numerous songs for other artists, this is the first time she's worked with Pink in an official capacity — and we hope there's more to come.
