Lady Gaga made a big entrance at this year's Grammy awards, being carried down the red carpet in a giant egg!
The Bad Romance singer went on to break out of the shell on stage to perform her latest single, Born This Way.
It was a good night for Lady Gaga as she also won three of the six awards she was nominated for, including best pop album for Fame Monster and best female pop performance.
Justin Bieber performed with Usher, but went home empty-handed after losing out to a singer called Esperanza Spalding in the best newcomer category.
It was a better night for Usher, who won two awards - best R'n'B album for Raymond vs Raymond, and best male R'n'B performance.
Rihanna's Only Girl in the World was named best dance recording.
And British group La Roux looked delighted to win the Grammy for best electronic dance album.
Katy Perry took two guests to the star-studded ceremony - her husband and her grandma! Check out her grandma's sparkly walking stick!
Fans loved Katy's performance on the night, but she didn't win any of the four awards she was shortlisted for. Better luck next year Katy!
