One of the biggest nights in the world of music took place on Sunday in Los Angeles in America. U2 were the first act on stage at the Grammy Awards.
But it was British acts who stole the show. Radiohead won two Grammys and performed on stage with the marching band from the University of Southern California.
Justin Timberlake was another big name to perform, alongside rapper TI. Perhaps it was cold at the Staples Center because they both look dressed for cold weather...
Coldplay won one of the biggest prizes of the night, song of the year, for Viva la Vida. But seriously boys, what's going on with those jackets?
Later Chris Martin got behind the piano to perform a special version of Lost! with his pal Jay-Z.
Adele won two Grammys - and beat The Jonas Brothers to the prize for best new act. She also won the snappily titled best female pop vocal.
It seemed a big night for unexpected team-ups, with those Jonas Brothers lining up with legend Stevie Wonder to perform a mix of their track Burnin' Up and Stevie's Superstition.
Miley Cyrus was another top pop act to perform on stage, alongside Taylor Swift.
MIA made sure no-one failed to spot her. She's due to have a baby any day now but it didn't stop her posing for photographers...
...or getting on stage with some of the biggest names in rap - Kanye West, Lil Wayne, TI and Jay-Z. Lil Wayne won three awards including best rap album.
