Gaga made headlines earlier this week when she played a show in Amsterdam and debuted some outfits which were decidedly…tight.

The petite performer now says she’s dieting in an effort to remove some extra poundage gained while on tour, and despite rumors that she’s pregnant, she says she’s just “bulked up” from the rigorous tour schedule.

“I’m dieting right now, because I gained, like, 25 pounds,” Gaga said. “And you know I really don’t feel bad about it, not even for a second. I have to be on such a strict diet constantly. It’s hard because it’s a quite vigorous show, so I tend to bulk up, get muscular, and I really don’t like that. So I’m trying to find a new balance.”

Gaga says she loves pizza and pasta, like any New York girl, and because she’s so petite, even a few pounds gained can seriously alter her body. And although some have said that alcohol is to blame for her sudden weight gain, Gaga blames her dad, who owns a restaurant in New York.

“It’s so amazing … it’s so freaking delicious, but I’m telling you I gain five pounds every time I go in there,” she said. “So my dad wants me to eat at the restaurant, and I’m, like, I’ve got to go where I can drink green juice.”
