Jennifer Lopez "definitely" wants more children.

The singer-and-actress already has one-year-old twins Max and Emme with her husband Marc Anthony and is keen to expand her brood in the future.

She said: "I definitely want to have more though. I don't know if it's in the cards for us, but I would like to."

Although the 39-year-old star now feels ready for more children, she admits Marc, 40, has been desperate for her to get pregnant again for some time.

She said: "I was like, 'Let me work just a little bit first, Let me get a couple things out there one song, one movie, something.' Marc is like, 'What are we waiting for?' "

Jennifer revealed motherhood has changed her more than she thought it would, adding she finds it hard to be parted from her children.

She added to US TV show 'Access Hollywood': "Everything I do is always about - I just got to get back to see the babies. What time am I going to be able to get back?

"I have to start thinking about travelling without them and that's a big traumatising thing for me now. I'm going to have to learn how to balance it."
