Jennifer Lopez and Ben Affleck have been spotted in multiple states around the country over the last month and it looks like their most recent reunion in Miami featured some PDA.

The duo, dubbed "Bennifer" by fans during their engagement over a decade ago, recently took their travels to Miami, Fla. where an onlooker spotted them working out together at a gym.

According to a source, the singer and actor weren't hiding their rumored romance as one person spotted them sharing "a kiss between sets," Entertainment Tonight reports.

Lopez and Affleck's outing reportedly took place at Anatomy Fitness in Miami. "They went to do their workouts with separate trainers, but were not trying to hide their relationship by any means," the insider dished.

While the two were each working on their fitness, they were spotted "hugging" and "being playful together." The source added that it was "clear to everyone that they have intense chemistry and were having fun together."

"They were having a good time," the source added. "Jennifer works out every day and it's part of her routine and it seemed like Ben really wanted to be there too with her." 

The eyewitness concluded that the two appear to be in the "honeymoon phase." Lopez and Affleck's alleged rekindled romance has been the talk of Hollywood, with fans and stars weighing in with an immense amount of support for the couple to become official once again.
