Jennifer Lopez laughs with love

Jennifer Lopez thinks laughter is the key to her successful marriage.

The singer-and-actress - who has three-year-old twins Max and Emme with spouse Marc Anthony - says she originally fell for his sense of humour, and believes their shared sense of fun has helped them stay together.

She said: "Our secret is being able to laugh together. He's a funny guy - it's what I've always loved about him.

"We also have a real connection which is based on a lot of love and laughter."

Jennifer also revealed she thinks using social networking website twitter has brought her closer to her fans and she even thinks of them as her friends.

She said: "My friends call me Jen or Jennifer, and my fans call me J-Lo, which I still like very much too.

"But it's funny with twitter and all these ways to communicate, you kind of feel like your fans are your friends.

"They're much more a part of the process now and I love it.

"When I did my first album we didn't have anything like that."
