The singer-and-actress recently announced her split from third husband Marc Anthony – father of her three-year-old twins, Max and Emme – and even though she has three failed marriages behind her, Jennifer is confident she will find happiness again.

She said: "This was the hardest decision I've ever had to face. I really wanted this family to work. That was my biggest dream, and I worked hard at it. We both did. Sometimes it doesn't work — and that's sad. But I remain an eternal optimist about love. I believe in love...It's still my biggest dream."

The interview mostly took place before the break-up was announced and the 'American Idol' judge revealed she and her singer spouse were struggling to get the right balance between work and family life.

The 42-year-old beauty – who wed Marc in 2004 – told America's Vanity Fair magazine: "It's getting increasingly harder. When we were first married, most of the time, and even before the babies were born, we were able to go everywhere together. I wasn't working as much. So we kind of had that. I went on tour with him a few times in the first few years of our marriage, and we did a film together. It's hard, and we're figuring it out. It's tough.

"And everything is ramping up in a way. Like I said, we had the first three years of our marriage just for us. I wasn't working, it was mainly about him. Then we got pregnant. Then it became about the kids. And then I started working again."
