Jennifer Lopez doesn't want her children to have a 'weird existence'.

The 'Back-up Plan' actress – who has two-year-old twins, Max and Emme, with husband Marc Anthony – is keen to keep her family life private as much as possible because she knows too much attention could have a bad effect.

She said: "We're not ones to parade the kids around. Marc is really adamant about that. He's really protective. We don't want them getting used to that life. It's a weird existence. I used to be of the attitude, many years ago, that I would just live my life and not care. But at the same time, you shouldn't just throw caution to the wind, because there are consequences to that lifestyle."

Although she and Marc would like to do lots of things together, the 40-year-old beauty feels a 'responsibility' to her fans to work without her spouse.

Jennifer – who married Marc in 2004 – told the USA Today newspaper: "The first two years we were kind of in wedded bliss. The third and fourth year, we just did everything together. He produced my album. We did the movie 'El Cantante'. We went on tour. We had the babies. We just got to the point, after the babies were born, when we realised that he has a responsibility to his fans and I have a responsibility to my fans. We still are two individual entities and artists, and we have to go off and do our things again. He's going to start his salsa album now."
