Jennifer Lopez has learnt about the sexes since the birth of her twins.

The 40-year-old beauty claims having Max and Emme, now two, has helped her develop her understanding of the differences between men and women.

She is quoted by gossip website Absolute Now as saying: "Having a little boy and a little girl has helped me to understand the differences between men and women.

"It's so obvious. Max is very boy-ish and runs everywhere but doesn't think too much. Just like a guy really. Whereas Emme is a little thinker. Women think too much and men don't. It's finally helped me to understand the dynamics between them."

The actress and singer recently admitted she was finding it hard to leave her children and head out to work.

She said: "They're at the point now where they've come to the door and started yelling, 'No, no, Mommy, don't go!' And I was like, 'Whoa, this is bad'.

"That's really tough. So I'm just going to have to figure it out as I go along. I keep trying to explain to them, 'I'll be home and the sun will still be out!'"
