Madonna has confessed she is a "crap mother." The Hung Up singer - who has a daughter Lourdes, nine, and a five-year-old son Rocco - made the startling confession as she complained about the ongoing struggle of juggling work and motherhood. She said in an interview with fashion designer Isaac Mizrahi: "It's a struggle to balance my career with my children.

"I'm always going, 'Oh God, I'm a crap mother'. I want to get home and put my kids to bed. And then sometimes, if I'm spending a lot of time with my children, I think, 'Oh God I just want to be an artist.' And you know it's hard."

The 47-year-old singer also admitted that Lourdes - whose father is Madonna's former personal trainer Carlos Leon - often gets frustrated by her mother's fame.

She said: "Sometimes she doesn't want me to come to certain things because she knows everyone is going to pay attention to me and then they'll treat her differently."
