The 29-year-old Burlesque singer split with husband Jordan Bratman last month. She revealed that although she is finding it tough, she is concentrating on making the split as easy as possible for son Max, two.
Appearing on The Tonight Show With Jay Leno, the star said, 'It's hard, definitely. It's hard just even being a working mum and trying to balance and juggle everything on your plate.
'I like to be the first thing Max wakes up to in the morning and the last thing he goes to bed at night seeing and singing him his lullabies before bed. It means the world to me to be able to do that.'
