Beyonce Knowles claims she and husband Jay-Z love changing their daughter's dirty diapers.

The 'Halo' singer and the hip-hop star welcomed little Blue Ivy into the world in January and are loving every moment of parenthood, including the not-so-glamorous parts.

She said: ''Actually, [Jay-Z] is very good. We both [change diapers]. I love changing diapers, I love it. I love every moment of it, it's so beautiful. I love it all.''

Beyonce also revealed how she likes to make up songs for Blue Ivy to send the tot to sleep.

In an appearance on TV show 'Anderson Live, she revealed': ''I make up actually a lot of crazy, corny songs.''

However, while she sings songs at home, Beyonce admits her little girl gets confused when she sees her perform in front of an audience.

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

Jay is equally as besotted with his daughter and recently revealed she ''doesn't have to be tough'' when she grows up.

The rapper - who had a hard upbringing - said: ''She doesn't have to be tough. She has to love herself, she has to know who she is, she has to be respectful, and be a moral person.''
