This marks the singer’s fourth marriage. Marc and J.Lo split in 2014 after a 10-year marriage. HollywoodLife learned EXCLUSIVELY that the former spouses are dedicated to co-parenting their children. “One of the reasons Jen and Marc’s co-parenting relationship works so well is because they keep their conversations all about the kids. The only thing that matters to her is that anybody he’s with is good to Max and Emme,” a source told HollywoodLife.
