Jennifer Lopez has hinted she would like children with her boyfriend.

The 43-year-old actress-and-singer has four-year-old twins Max and Emme with her estranged husband Marc Anthony.

She is now in a relationship with 25-year-old backing dancer Casper Smart and admits motherhood has been on her mind lately.

"I haven't closed shop in that department," she told British newspaper The Sun. "I don't know, we have to see - we only have so many years that you can do that."

Jennifer recently quit her seat on the American Idol judging panel so she can focus on her singing career and spend more time with her children.

The superstar explained family is the most important thing to her, which is why she is considering expanding her brood.

"I am a lover. I mean, at my core I feel like that's such a big part of my personality - and a part of why I do what I do - because I have so much to say on that subject," she said.

"I feel like that's what my life is about."
