Jennifer Lopez and Estranged Husband Ben Affleck Reunite Ahead of Christmas

And while Ben and J.Lo have let the sun set on their romance, they have proven to be on good terms beyond family affairs. After all, the couple worked together on the film Unstoppable—which Ben co produced, while J.Lo starred.

She even lauded the experience of working alongside her ex on the movie—which was filmed in the months leading up to their divorce.

“I would describe all of the cast and everybody behind the scenes,” she told a reporter during the film’s U.K. premiere last month, “as spectacular and wonderful.”

Meanwhile, Ben, 52, also didn’t hold back on celebrating the crew—including his ex.

“We really believe in the power of storytelling when the people involved in it are deeply connected to the story,” Ben explained to Entertainment Tonight last month. “Jennifer’s spectacular.”

As for where the couple stands romantically? The “On The Floor” singer has made it clear that she’s focusing on herself right now.

“I can’t be looking for happiness in other people,” she said in an Interview magazine article published in October. “I have to have happiness within myself. I used to say I’m a happy person, but was still looking for something for somebody else to fill, and it’s just like, ‘No, I’m actually good.’”

Although they’re better off as friends, J.Lo and Ben’s romance was unforgettable. Keep reading for a look back.
