There's no place like Good Morning America for Lady Gaga to perform a Wizard of Oz-themed version of her hit single, "Applause."

The pop star stopped by the morning show in full Dorothy glam, complete with multiple wardrobe changes.

Gaga began the musical number by singing "Somewhere Over the Rainbow" and walking down a yellow brick road.

Dressed in her own version of the famous blue gingham dress, Gaga clung to her pet pooch Fozzi, who played the role of Toto seamlessly.

She later changed into a Glinda the Good Witch costume, then an all-black leotard, and finally finishing the theatrical performance in an oversize blue blazer.

The New York native wore a pair of custom sequined ruby slippers and had been posting Instagram pics of them over the last few days.

"Always sleep with my dance shoes before a performance," she wrote on one photo. "There's no place like home. #Applause"

Mother Monster also took the stage to address Azealia Banks' recent war of words against the singer.

While speaking privately to fans, Gaga is overheard saying, "She's got a bad attitude," when asked about the rapper.

And boy oh boy did Banks have something to say about that.

She tweeted (and attached a link to the clip of Gaga's comment), "Lady gaga looks so nervous and scared here lol, she's like "don't record this" hahaaaa."

Banks recently took to Twitter to vent about how she felt that Gaga was copying her mermaid style.

"Of COURSE gaga wants to play mermaid again….Pffft," she added. "Not picking a fight. Just all looks soo familiar….To me."

She concluded her diss-session with, "It's just…Late."

And up until now, Gaga had remained mum on the rapper's accusations.
