Beyonce Knowles is really impressed by her husband Jay-Z's diaper changing skills.

The superstar singer and her music mogul beau welcomed daughter Blue Ivy into the family in January.

Beyonce and Jay-Z are having a lot of fun together tending to the baby's needs.

"Actually, [Jay-Z] is very good. We both [change diapers]. I love changing diapers," she told Anderson Cooper during an interview on Anderson Live.

"I love it. I love every moment of it, it's so beautiful. I love it all."

Beyonce sings sweet lullabies to Blue Ivy.

She confesses that many of the tunes come from the top of her head.

"I make up actually a lot of crazy, corny songs," she laughed.

Although Beyonce is known as a legendary talent around the world, her little tyke doesn't relate to her in that way.

The star isn't used to her mother's powerful stage persona.

"I'm Mommy and when [Blue] sees me today was the first time she saw me perform in rehearsal she was very confused," Beyonce said.
