Jennifer Lopez Reportedly Back With Ben Affleck Weeks After Alex Rodriguez Split: ‘The Chemistry is Unreal’

Jennifer Lopez wasted no time in replacing Alex Rodriguez.

The pop music superstar had been hanging out with Ben Affleck in Los Angeles following Lopez’s public split with Alex Rodriguez. Their hanging out has been taken a step further as the two reportedly jetted off to Montana for a weeklong couple’s vacation.

A source tells E! News. “They were alone,” says the source. “Just the two of them.”

“They have been in touch here and there throughout the years,” a second source close to Jennifer told E! News, noting the duo reunited after she returned from filming in the Dominican Republic. “Ben reached out to her to see how she was doing and they had dinner together a few times within this last month. 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.”

Jennifer and Ben began dating in July 2002, but days before their September 2003 vows, the couple called off their Santa Barbara, Calif. wedding. Months later, in January 2004, they confirmed they had officially split.

Prior to the Montana sighting, Lopez and Affleck both attended and participated in the VAX LIVE: The Concert to Reunite the World event, which aired on Saturday.

“They have a lot of love for each other. They have always admired each other,” a source recently told PEOPLE of Lopez and Affleck.

This news comes after she and ex-fiancé Alex Rodriguez released a joint statement on April 15 announcing the end of their engagement.
