The 27-year-old singer, who has admitted her weight fluctuates because of her love of Italian food, has been gorging on barbecue food and meat during her stay in Austin, reported E! online.
"That's actually why I wore it because I am really fat right now because I have been eating BBQ. I had some at Stubb's because I am playing there and some Salt Lick too. Or any meat that I find on the street, I just eat," the singer said.
