Lopez 'spends every free moment with kids'

Jennifer Lopez has revealed that she spends all her free time with her children.

The 39-year-old, who gave birth to twins Max and Emme in February, told People: "I try to take breaks from work. I'll do a little work with the choreographers and then come back. I try to spend every free moment with the babies."

Lopez added that she often sings lullabies to her twins to send them to sleep.

"When they see you and have that big smile on their face - I live for that," she said.

"And when I put them to bed at night, and they melt in your arms. I give them a bottle and wind it down. I say, 'It's time for beddy-bye'. I hold them and sing a little song. By the time you know it, they are asleep."
