"I thought, well I don't really care if they think I'm fat, because, quite honestly, I did gain about 30 pounds," she admitted. "Adele is bigger than me, how come nobody says anything about it?"

But she quickly clarified this to be a compliment.

"She's so wonderful and I think her confidence is something I have to match," she said about the Grammy award-winning artist. "She has set the bar very high for a lot of woman. I need to be a confident woman and just say politically active things when I can that are helpful to young people."

Gaga has continued to be outspoken about her weight gain, starting her Body Revolution campaign -- which is about encouraging fans to celebrate their flaws -- in September.

Though she did reveal to Stylist that she still has a common insecurity you wouldn't expect from a worldwide superstar.

"Do you know what's really funny, and I was kind of afraid to admit this, but I'm just going to say it anyway, 'cos I think my fans will really appreciate it. I am throwing my best friend an engagement party this weekend, and I'm going to be seeing all these girls from high school, and I would be totally lying to you if I didn't say I was worried about how I'm going to look!," she admitted. "I was saying earlier, 'I have to look fabulous, I have to look absolutely amazing, some of them were horrible to me!'"
