Grammy-winning singer Beyonce Knowles-Carter boasts about her never-ending work ethic and why she deserves to dominate any facet of the entertainment business these days in the new issue of GQ.

In Bey's cover feature, she describes just how much time and effort has gone into molding her career.

"I worked so hard during my childhood to meet this goal: By the time I was 30 years old, I could do what I want," she says. "I've reached that. I feel very fortunate to be in that position. But I've sacrificied 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." (GQ)
