The couple ended their marriage for the sake of their two children, a family source tells PEOPLE
But after news broke Friday that the power couple were ending their marriage, a source close to the family tells PEOPLE that Anthony, 42, and Lopez, 41, who have two children, 3-year-old twins Max and Emme, together, split “after months of nonstop arguing.”
“Marc and Jennifer decided it’s best to go their separate ways for the sake of their two kids,” the source says.
Anthony spent the weekend in Colombia, where he put his marital woes aside to put on an upbeat performance. The only reference to his marriage came in the form of a joke. “They’re saying I’m single,” he told the audience.
Meanwhile, Lopez was back to work Sunday at Milk Studios in L.A., where she was shooting an ad campaign for her Kohl’s fashion line.
“Jennifer is doing okay,” the source says. “In the past two weeks, she has spent a lot of quality time with her kids and her family in L.A.”
The source adds: “She is, of course, sad that she and Marc didn’t work out, but they both feel they have tried everything.”
