Katy Perry stole the show at this year's Grammy nomination concert in LA. She's got some tough competition for the best album award from one of the UK's finest... Susan Boyle!
What a winter wonderland! Katy was hoping she could out sparkle Lady Gaga both on stage and off. Both stars are up for up for best female performer prize...
But it isn't easy to out shine Lady Gaga - especially when she's wearing a bedazzled wig! Lady Gaga is up for a mega six awards, including one for her duet, Telephone, with Beyonce.
Selena Gomez and Dave Grohl from rock band the Foo Fighters announced the nominees for song of the year, including rapper Eminem's Love the Way You Lie, featuring Rihanna.
Eminem got a whopping 10 nominations! Rapper B.O.B will be hoping to beat him to win the prize for record of the year though. He also gave a stonking performance on the night.
Rock on! Paramore singer Hayley Williams look pretty happy with her band's nomination for best pop group.
Hayley showed just how big a hug she wanted to give Justin Bieber after announcing the best newcomer nominations.
