The Batman star, 49, and the 52-year-old were photographed together in the back of a black SUV as they departed the red carpet premiere of the coming-of-age drama that he stars in alongside friend George Clooney. Affleck puffed on a cigarette as he rolled down the window to sign autographs for fans at a red light.
Lopez, who did not attend the screening of the film, sat beside her boyfriend as he was pictured guzzling on water and lighting up a smoke.
The Maid In Manhattan actress was reportedly not at the movie's launch due to a specific person's presence. As OK! previously reported, Lopez "cannot stand" Clooney.
A source told The Sun, “Jen famously did not get along with George Clooney when they made Out of Sight together. They couldn't stand each other. So it's funny that Ben's new movie is with George and it's no coincidence that Jen was not photographed on the red carpet with him, posing with George and [wife] Amal."
Lopez and Affleck have been inseparable since they got back together this spring. The Tinseltown power couple have been spotted kissing in parks, attending movie premieres in France and have even been seen hanging out with Affleck's best bud Matt Damon since they revived their relationship. The actor and the triple threat have also sparked engagement rumors after the Good Will Hunting star was seen shopping for engagement rings.
As OK! exclusively reported, Lopez and Affleck "feel so blessed" to be continuing their love story all these years later. “Things just keep getting better for J.Lo and Ben. All the support means so much to them," a source dished.
