Jennifer Lopez and Marc Anthony at the Childrens Health Fund 20th Anniversary Gala held at the Hilton. New York City, USA - 30.05.07

The high-profile couple try to avoid conflicting schedules so they can spend as much time as possible together.

J.Lo tells American magazine Glamour, "We made all these promises to each other in the beginning of the marriage, because both of us have difficult careers to manage with a partner.

"We don't have nine-to-five jobs; our day could be 24 hours long if we let it. So you have to carve out your time and make your agreements: 'We are going to travel with each other. If I'm working, you're not going to work. If we both have to work, we're going to make sure we keep that to a minimum.'"
