Jennifer Lopez finds being a single parent hard.

The 45-year-old singer-and-actress split from Marc Anthony, the father of her six-year-old twins Max and Emme, in 2011 and admits there are few positive aspects to not having the kids' dad around all the time.

She said: ''In the same way that two people are needed to create a child, is also easier to educate them if there are two.

''When you are a single mum, the only positive thing is that your children are all for you.''

The 'On the Floor' hitmaker - whose own parents are divorced - admitted the twins sometimes cry because their father isn't around but she does her best to reassure them it doesn't mean he doesn't love them.

She told France's Gala magazine: ''When the twins cry because their father isn't with them, I always say to them that mine isn't with me either but that doesn't stop me feeling his love.''

And though she is currently happily single, Jennifer - who has been romantically linked with dancer Maksim Chmerkovskiy and choreographer JR Taylor since splitting from boyfriend Casper Smart in June - says any man she dates in the future must care about her kids.

She said: ''In the future, I will be sure that the man who I will be with will worry about Max and Emme's well being.''

The 'American Idol' judge credits having a good routine for her ability to juggle her work with raising the twins.

She explained: ''I get up at half past six in the morning, and I finish working at about seven o'clock in the evening.

''I stop to cooking dinner for Max and Emme and I take them to bed at nine. Once they're sleep, I go back to work until I'm tired.''
