Ben Affleck and Jennifer Lopez are Instagram official, thanks to Leah Remini

While the pair have been spotted together several times since reportedly rekindling their 2000s-era romance in April, Ben Affleck and Jennifer Lopez have kept their coupling off Instagram -- until now.

Thanks to a snap from a slideshow on Lopez's friend Leah Remini's Instagram page, the couple have been captured together on the social media platform for the first time.

Remini shared a series of black-and-white pictures from a photo booth that had been set up for her recent 51st birthday party. Among them is a snap of the buzzed-about couple.

It shows Lopez striking a pose under the crook of a smiling Affleck's right arm, her hand on his chest. Remini's under Affleck's left arm, with her hand on his chest as well.

Remini commented to her 2.9 million followers: "Wanted to share a little video from my birthday with you all because I got so much love from you on my birthday but also everyday [sic]. I consider myself to have the best support system here on social media."

She added: "Also, I can't thank my family & friends enough for coming, for celebrating with me in a way that was very special to me. It's been an interesting year, so this birthday meant a lot for many reasons."

Lopez, 51, and Affleck, 48, first began dating in 2002 and got engaged later that year. They broke up in 2004. Affleck went on to marry actress Jennifer Garner, with whom he has three children, and Lopez wed singer Marc Anthony, the father of her twins. Affleck and Garner split in 2015. Lopez and Anthony ended their marriage in 2011 and she went on to get engaged to former major league baseball player Alex Rodriguez. They confirmed their break-up this past April, shortly before Lopez was photographed with Affleck.

Earlier this week, People magazine reported that their relationship is pretty serious.

"They want to do everything they can to make this work," a source close to Lopez told the magazine.
