Jennifer Lopez constantly worrying

The singer-and-actress - who has two-year-old twins Max and Emme with husband Marc Anthony - admits she is constantly worrying about her family and rarely gets time to indulge her own interests.

She said: "I don't really believe mothers have time for themselves.

"It's always on your mind, even when you are trying to relax and get away - it's just one of the absolute facts of being a mother."

However, the 41-year-old beauty admits she does get some time to be alone when she is working on a music or film project.

She said: "That's when I have time to concentrate on what I'm doing, but as far as leisure time, mothers don't get that - it's just part of the deal."

Jennifer also admits she has learned to lead a life away from the paparazzi after years of being followed by photographers.

She revealed: "I take my kids outside and we do things, but I'm careful about where I take them. Marc and I want our work to be the focus of what we do.

"We understand some of our private life comes into that, but it's better when that's not the whole thing."
