This isn’t a rehearsal: Jennifer Lopez and Ben Affleck are transitioning from friendly exes to…something more, seventeen years after calling off their engagement. After appearing separately at the VAX LIVE concert in Los Angeles on Sunday, May 2, the stars jetted off to the Yellowstone Club in Montana, where they spent about a week together, according to an E! News outlet. “They were by themselves,” the source claims. “It’s just the two of them,” says the narrator.

Lopez and Affleck can be seen driving together in Montana in photographs captured by the Daily Mail. Jennifer and Alex Rodriguez announced their breakup after four years together around a month ago. She and A-Rod reunited briefly in late April in L.A., he wanted to “iron things out” with her. Ben, on the other hand, was later discovered at her city residence. Another source said they were “just friends” at the time.

However, the two quickly discovered that their chemistry could not be ignored. “They’ve kept in contact here and there over the years,” another source close to Jennifer told that, adding that the two reconnected after she returned from filming in the Dominican Republic. “Ben contacted her to see how she was doing, and the two of them had dinner together several times in the last month. It’s completely normal between them, and the chemistry is incredible. They’ve picked up where they left off and are currently enjoying each other’s business.”
