Beyonce is crazy in love with motherhood -- even diaper duty!

In a new interview with Anderson Cooper on the season premiere of Anderson Live, airing Monday, the 31-year-old singer gushes about life at home with daughter Blue Ivy, 9 months, and husband Jay-Z.

"I love changing diapers," the Grammy winner reveals. "I love it. I love every moment of it, it's so beautiful. I love it all!"

And her husband of four years Jay-Z (real name: Shawn Carter), 43, is in on the act as well. "Actually, he is very good," she explained of the rapper's diaper skills. "We both [change diapers]."

And little Blue has no clue that her mom is global superstar. "I'm mommy, and when [Blue] sees me, today was the first time she saw me perform in rehearsal, she was very confused," admitted Beyonce, who has given a handful of concerts and performances since giving birth in January.

Not that Blue hasn't heard her mom's golden singing voice.

To get Blue into slumberland, Beyonce sings plenty of lullabies -- but not necessarily her own hit ballads like "Halo." "I make up actually a lot of crazy, corny songs," she says.

Beyonce, Jay-Z and Blue have spent the past week in the South of France, where the family celebrated the new mom's 31st birthday.
