This kind of makes the Destiny's Child reunion sound like it'll be the Beyonce show -- Bey says she's the hardest-working woman in showbiz.

She tells GQ that whatever success she's achieved, she's worked hard to achieve it. "By the time I was 30 years old, I could do what I want. But I’ve sacrificed a lot of things, and I’ve worked harder than probably anyone I know, at least in the music industry. So I just have to remind myself that I deserve it.”
