Katy, 34, stormed the stage in New Orleans amid a very colorful background.
The "Fireworks" singer wore an elaborate leather ensemble that resembled a piano.
It was during her time there that Katy randomly talked about her potential bun in the oven.
"I want to let it be known that I am not pregnant," Katy joked to the crowd while holding on to her stomach. "This is just yesterday, and I am proud of it."
Katy discussed indulging in Southern cuisine like fried okra during her time in New Orleans.
The American Idol judge is currently engaged to fiancé Orlando, 42. He has one child from a previous relationship with model Miranda Kerr.
