Even superstar couples don't always see eye to eye. Madonna and Guy Ritchie reportedly can't decide on their children's education. The couple have been said to be in constant disagreement about where to keep their kids in school.

Guy has grown increasingly unhappy with his wife taking Lourdes, nine, and five-year-old Rocco with her on her current "Confessions" world tour.

The "Snatch" director is reportedly fed up with the constant upheaval and has demanded the children be left in one place when the new school year begins next week.

A source told Britain's The Sun newspaper, "The kids already have schools in London and Los Angeles which they float between. Madonna thinks it's good for her children to be with mom and see the world but Guy disagrees-he's more traditional. It's causing a lot of tension."

Earlier this year, Madonna confessed she was a "c**p mother."

The 48-year-old singer admitted she was finding it a struggle to balance her career with being a parent.

"It is a struggle to balance my career with my children. I'm always going, 'Oh God, I'm a c**p 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'," she said.
