Jennifer Lopez 'couldn't be single mum'

Jennifer Lopez has revealed that she would find it too difficult to be a single mum.

The actress, who gave birth to twins in 2008, is currently starring in The Back-Up Plan, about a woman who gets artificially inseminated.

"I know a couple of people, both people I work with and friends, who have done this," Lopez told USA Today. "I just don't know if I could do this, honestly. Now I know how much I rely on my partner [Marc Anthony]."

However, Lopez added that she admires women who decide to have children on their own.

"Knowing what single mums go through, I think it takes such an amazing person to do that," she said. "You get to a point in your life and you think about it, and I think it's a beautiful thing to be able to find the strength to do that on your own.

"That child will enrich your life. It's a beautiful thing to think that option is there."
