Singer-actress Jennifer Lopez feels it's tough being a single parent to her six-year-old twins -- Max and Emme, whom she has with singer Marc Anthony.

"Just like we need two people to create a child, it is easier to educate them as a duo. As a single parent, the only positive thing is that your children are all for you," the 45-year-old, who separated from Anthony in 2011, said to Gala magazine, reports femalefirst.co.uk.

Lopez and Anthony started dating back in 2004, and got married that same year.

Lopez herself was brought up by divorced parents.
