Can we just talk about how fantastic Pink is for a second? The pop star just blew our socks off with an amazing acrobatic performance at this year's Grammy Awards [1]. She and Nate Ruess duetted to "Try" and "Just Give Me a Reason," and Ruess was great and all, but Pink's skyborne moves were beyond compare. How does she sing while spinning upside down like that? Take a look for yourself.
