Ben Affleck and Jennifer LopezThe reunion is heating up, and we have the pictures to prove that there’s still a lot of chemistry between the two.

The formerly engaged couple, who split in 2004 after a much-touted romance, have spent considerable time together in recent weeks after being spotted at Jennifer’s Los Angeles mansion for the first time in April. The news follows J.Lo’s separation from her long-time fiancĂ© Alex Rodriguez and months after Ben’s relationship with his Deep Water co-star ended Anna of Arms. Now it seems to be getting serious again: In addition to their vacation together in Montana in May, the two were recently seen on a date in West Hollywood, California.

The two were joined by J. Los’s manager Benny Madina and film producer Elaine Goldschmied-Thomas. An eyewitness said of the couple: “Ben had his arm around Jennifer at dinner and they weren’t afraid to be loving. He looked great and seemed very happy. She looked happy too and continued to lean against him. “
