The outspoken singer appeared on the show wearing what she called a latex condom-inspired outfit.
On Sunday, she took home Grammy Awards for best pop vocal album and best female pop performance.
But most of the attention was focused on her over-the-top arrival in a plastic egg.
When "Good Morning America" co-host Robin Roberts asked the eclectic performer how long she stayed in the egg, Lady Gaga said she was in the oval contraption for three days.
"I was viva-glamming for three whole days, because I wanted to have a rebirth, and I think the universe needs to have a rebirth," the singer said.
Gaga is also promoting a new Mac lipstick with all proceeds going toward AIDS education and prevention.
