Ri hit the Grammys stage on Sunday night (Feb. 8), to perform her new single "FourFiveSeconds," with some assistance from former Beatle Sir Paul McCartney, and Kanye West, and...why aren't they just a band already?
First of all, all three of them wore almost the same outfit -- a black suit -- just adding their own individual touches to make it unique.
They stood lined up next to each other, just like real band members do, and pretty much complemented each other in every way possible.
While Rihanna and Kanye had some vibing sessions face-to-face, where they really looked like they were a few seconds from wylin', Paul McCartney was strumming away on his guitar and singing with a huge smile on his face.
Oh, and how about Kanye calling him out by name during the performance -- "Paul!" -- only real band members could do that.
Tonight, we also learned that Kanye and Rihanna have a lot more collaborations on the way. When? We don't know.
