There are three very important girls in Keith Urban's life -- his wife Nicole Kidman and their daughters Sunday and Faith.

And according to Us magazine, it sounds like beyond being the loves of his life, they are also teaching him a thing or two about a thing or two.

"I didn't grow up with any girls in my family,” Urban said during last week's CMA Music Festival in Nashville. “It was just my brother and me and mum and dad. Now being in a family that is all girls, I'm learning an enormous amount."

I'm sure Sunday, 6, and Faith, 4, will continue to school Urban on all kinds of things until they grow up and leave the nest. In the meantime, Urban seems to be happy that he and Kidman see eye to eye on parenting.

"Nic and I are very in sync with the way we want to raise our girls," he said. "(We maintain) a very expressive, artistic house. I'm very comfortable with it."
