Beyoncé: "I Love Changing Diapers"
Jay-Z is also a bit of a pro when it comes to the task.
During an interview which airs today (10th September), Queen B revealed: "Actually, he's very good. We both do [it]. I love changing diapers, I love it. I love every moment of it. It's so beautiful."
When probed by Cooper whether she genuinely likes the job, Bey replied: "I really do. I love changing diapers - I love it all."
The I Was Here singer went on to reveal that she often sings nursery rhymes to Blue Ivy, as well as making up her own "corny" tunes.
She said: "Today was the first time [Blue Ivy] saw me performing in rehearsal - she was very confused.
"I make up actually a lot of crazy, corny songs. [But] I'm not singing it. Unless you do 'Single Ladies'!"
