"Marc and I are good partners," Lopez tells Entertainment Weekly magazine in its April 6 issue. "We love each other. We want to be the best person we can be for each other. And we work on that. That's what a real relationship is about to me."
The couple wed in June 2004.
"When we got married, I was like, 'I've been working for I don't know how many years at (a high) level of intensity and exposure,' " Lopez says. "I'm going to get back to what originally drew me to expressing myself as a creative person."
The 38-year-old singer-actress was previously married to choreographer Cris Judd and waiter Ojani Noa. Anthony, 37, was married to former Miss Universe Dayanara Torres.

Lopez recently released her first all-Spanish album, "Como Ama una Mujer (How a Woman Loves)," which was mainly produced by Anthony.
The album "is an opportunity for me to show my emotions, vulnerability and passion," she tells the magazine. "I don't get to do that as much in English."
Lopez will perform "Que Hiciste (What Did You Do)," the first single from "Como Ama," when she appears April 11 on News Corp.'s Fox network talent competition, "American Idol."
