The US music world came out to play last night.
But it wasn't all fun and games. Some of them had work to do.
This year's three-hour ceremony boasted live performances from Beyonce, Lionel Richie, Jay-Z, Fall Out Boy, Gwen Stefani...
... Barry Manilow, Jamie Foxx, Pussycat Dolls, Josh Groban, Snow Patrol, Dixie Chicks, John Mayer, Carrie Underwood, Mary J Blige...
... Nelly Furtado, Rascal Flatts, Tenacious D and a duet from Snoop Dogg and Akon.
And for their efforts a few performers got their mitts on a much sought-after award.
