Pop star Lady Gaga, 26, got people buzzing during her Amsterdam concert that surfaced yesterday, and it wasn't because of her outfit for once, but what was inside it.

A fuller-figured looking Gaga hit the stage in skimpier clothing than she's been wearing recently, and everyone from the panel of The View to Kelly Osbourne, who's had to dodge her own weight-related publicity in the past, was wondering if Gaga was pregnant … or just packing on the pounds.

Osbourne's hunch told her that Gaga was hiding something. "I think she is pregnant because she has been covering up this part of her body recently and I have been noticing that a lot, and her style has changed and you can't bleach your hair blonde when you are pregnant," Osbourne deduced, reports Examiner. "I know nothing, but just my instincts are telling me: preggers!"

But it seems that all that intuition was for naught, as Gaga recently revealed the cause behind all the weight speculation. "I love eating pizza and pasta," Gaga said on Elvis Duran's radio show. "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 [Joanne Trattoria]. It's so amazing … 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."

Sorry, Kelly. And, what's more, Gaga doesn't mind going back-and-forth a bit. "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."
