The pop star said she could barely remember the event after partying the night away in Los Angeles, California.
“I know it was fun. I do remember being called ‘Drunky Gaga’ at some point,” she told US chat show host Jay Leno.
Asked how she celebrated her Grammy triumph, she admitted: 'I don’t remember.'
And she insisted that she had turned up to the music awards cocooned in a transparent “vessel” – not an egg.
“Hussein Chalayan, who designed it, he said: ‘Make sure you tell everyone it’s a vessel’,” she said.
“I was in there for three days. It was temperature controlled,” she joked.
