Lady Gaga has Tweeted about her Grammys win.
The singer won three awards, one for 'Fame Monster' and two for 'Bad Romance'.
She Tweeted: 'I'm so honored + grateful we won 3 GRAMMYS. BORN THIS WAY piece was pure joy for Haus to perform. Paws Up Monsters.'
The Born This Way star was carried along the red carpet encased a giant egg.
Her aides told reporters she'd spent 3 hours inside the egg breathing through an oxygen mask, before her arrival.
The star refused to speak to anyone on the red carpet because she was in 'incubation' ahead of the performance of her new single. "She's in an embryonic state and won't be born until the performance." said one of her team.
The Born This Way star went on to win three awards - including best female pop vocal and best short form video for Bad Romance. But her smashing evening didn't end there. The 24-year-old emerged from the glowing egg to perform her latest single Born This Way.
Jay-Z also won 3 awards - including best rap collaboration and best rap song for Empire State of Mind with Alicia Keys.
Paul McCartney won his first solo Grammy in 39 years for a live recording of Helter Skelter.
