Beyoncé 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.

Beyoncé 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.'

Beyoncé 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 Beyoncé 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,' Beyoncé said.
