Jennifer Lopez is relishing her reunion with former fiancé Ben Affleck.

The pair made headlines yesterday after news broke that they had flown to Montana to spend time at a resort together. Their trip reportedly happened shortly after their scheduled appearances at Global Citizen’s Vax Live benefit concert, filmed more than a week ago. The Daily Mail obtained photos of the two driving together around the state ahead of their return to Los Angeles.

“She had a great time with Ben,” a source told People of the pair’s reported rendezvous. “She is happy with him and enjoys spending time with him.”

An additional source told People on Monday that Lopez is surely enjoying herself, though it’s unclear if the former couple are indeed rekindling their romance.

“[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,” the second source revealed.

Though the pair called off their engagement almost two decades ago, they’ve reportedly stayed in touch over the years. Affleck also contributed to Lopez’s recent InStyle cover story, for which he praised her work ethic and career trajectory.

“I thought I had a good work ethic, but I was completely humbled and blown away by what she was committed to doing day in and day out, the seriousness in which she took her work, the quiet and dedicated way she went about accomplishing her goals, and then how she would go back and redouble her efforts,” Affleck told the magazine. “She remains, to this day, the hardest-working person I’ve come across in this business. She has great talent, but she has also worked very hard for her success, and I’m so happy for her that she seems, at long last, to be getting the credit she deserves.”
