Lady GaGa has addressed rumours that her aggressive touring schedule is wearing her out on stage.
According to PopEater, the 'Poker Face' singer announced more North American tour dates for 2011.
While performing on Monday in Sweden, GaGa said: "You know when people say, 'Lady GaGa's really tired, she needs to take a break', I just think about all those times I sang in bars when nobody was singing my lyrics. I'll sleep when I'm dead, okay?"
Later, she added: "I know that I work really hard and I run myself into the ground, and I also know that alcohol will kill me one day. But I would rather not die on vacation, I'd rather die on stage with all my fans."
