Lopez and the salsa superstar were married for seven years and are the proud parents of twins Max and Emme.
In an interview with People earlier this year, Lopez spoke about Smart’s impact on her life following her painful divorce.
“I just got out of a big, heavy, devastating thing, and he's helped me heal…He's been there for me,” she told the magazine.
Lopez also opened up about the uncertainty of their future.
“I think all different things. The truth is we don't know what's going to happen. We're loving this moment right now,” she said. “We make each other happy.”
