The 'Not Myself Tonight' singer loves spending time with her two-year-old son Max and husband Jordan Bratman after a long day being a pop star and has revealed she serenades Max to sleep with tracks from the musical movie 'Mary Poppins'.
She said: "I sing my son to sleep with 'Mary Poppins' [songs] and rock and cradle him and cover him up in bed and do really silly things that we won't even mention."
Christina is keen to have more children, but at present she is solely focused on her career and her new album 'Bionic'.
The 29-year-old star - who stars opposite Cher, Kristen Bell and Eric Dane in upcoming musical movie 'Burlesque' - added: "'Bionic' is definitely my baby at the moment. Eventually, in the future, I do want to expand on my family and have another one, but for now, 'Bionic' is the baby and 'Burlesque' is the other baby."
Christina has previously admitted the LP is inspired by Max.
She said: "'Stripped' was inspired by a lot of pain and 'Back to Basics' still had some sort of relation to my past.
"My new one is just about the future - my son in my life, motivating me to want to play and have fun."
