Kelly Osbourne has attributed the extra kilos to Gaga's supposed pregnancy, pointing out that the pop singer has been covering up her belly lately and has stopped bleaching her hair.
…and failing to factor in the joint that she smoked on stage during her Amsterdam show!
But Gaga has offered up the real explanation for her weight gain. Not that she should have to explain anything!
"I love eating pasta and pizza," the 26-year-old told radio host Elvis Duran. "I'm a New York Italian girl. That's why I have been staying out of New York. My father [Joe Germanotta] opened a restaurant. It's so amazing … it's so freaking delicious, but I'm telling you I gain five pounds every time I go in there. 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."
Gaga admitted she has gained 25lbs (11kg) indulging in her dad's delicious meals.
"I really don't feel bad about it, not even for a second," she said.
"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."
