"It's natural between them and the chemistry is unreal. They picked up where they last left off, and are enjoying each other's company right now."
And a source told People about how things are going between them after they were spotted together in a car in Montana.
"Jennifer spent several days with Ben out of town. They have a strong connection. It's all been quick and intense, but Jennifer is happy," they told the outlet.
Affleck and Lopez were together in the early 2000s and were engaged before breaking up in 2004.
