Jennifer Lopez Wore Another All-White Ensemble While Walking Around Capri With Ben Affleck

The romantic birthday trip continues. After a lavish weekend of yachting and clubbing (and butt-grabbing) around St. Tropez, Jennifer Lopez and Ben Affleck are extending their European tour. The couple took their luxurious (like $130,000,000-luxurious) to their next spot: Italy.

The lovebirds looked blissful as they took in the sights and sounds of the streets of Capri while holding hands and laughing. The "Let's Get Loud" singer looked tropical and ethereal in yet another all-white ensemble — her go-to this summer — with a wide-brimmed straw sunhat. She paired the fringed crop and draw-string short set with an oversized straw Valentino tote bag, square-toe nude strappy heels, stacks of bracelets, and gold aviator sunnies. The Argo actor paired a tight blue tee with beige trousers, white sneakers, and gold aviators.

As the two paraded through the street, J.Lo's crew followed suit, with her photographer snapping shots of the on-again couple. At one point, the couple stopped for an outdoor dinner and held hands across the table.

And they're both really as happy as they look. In fact, a source told Entertainment Tonight that their "relationship is serious."

"They have insane, on another level, chemistry," the source said. "They are both super passionate and are head over heels with each other, just like they once were. This time around, however, they both really feel like this is it."

The source added that everything about their relationship is "100 percent natural." "Once they rekindled, it was like no time had passed."

The source continued, "They couldn't be more in agreement. They feel at this point in their lives they were undeniably made for each other. Things between Ben and Jen have been easy and that's what makes their relationship work so well. They work seamlessly together and it's like their relationship hardly takes any effort."

Plus, their friends even approve. Affleck's close friend, Matt Damon said he was "so happy" for Affleck. At the premiere of his movie Stillwater, Damon told Extra that he's "glad for both of them."

"He's the best," he added. "He deserves every happiness in the world."
