Ben Affleck and Jennifer Lopez had a PDA-filled holiday over the July 4 weekend.

In photos obtained by Page Six, the two could be seen walking arm-in-arm and looked very in love. They are inseparable as they jet all over the world.

Before they were seen in Long Island, Lopez and Affleck were at Universal Studios in Los Angeles with their children Friday, Cosmopolitan noted.

They also showed how smitten they were with each other as they walked through the park's Simpsons-theme attraction called Springfield. Here, a source revealed they were walking shoulder-to-shoulder and holding each others hands.

A different insider told People in May that the 51-year-old singer was "open to having a relationship" with the actor. In fact, he wanted to spend as much time as possible with Jennifer Garner's former husband and see where their relationship would go.

They also found the beginning of their reunion coming at the right time as another tipster revealed they both had the same mindset after their respective breakups. Whether they would end up with each other or not, it was good for the two.

To recall, after parting ways with Ana de Armas and Alex Rodriguez, Affleck and Lopez are often seen out and about with each other again. They are now spending more time together and taking advantage of their free time to do so.

As they have already been in a relationship before, they are now getting to know each others children. Allegedly, the "Hustlers'' star is planning to move to L.A. from Miami with her twins.

Fortunately, the children have no complaints about their mother's plans. Maximilian David and Emme Maribel, whom Lopez shares with her ex-husband Marc Anthony, are on board with Lopez's scheme to start a new life in L.A.

They are now getting to know Affleck and it looks like everything is "running smoothly."

"It's very obvious that Jennifer is serious about Ben," the source says. "She hasn't looked this happy for a long time."

Alternatively, Affleck has three children with Garner, Violet Anne, Seraphina Rose and Samuel.

Affleck and Lopez rekindled their romance in April after ending their engagement in 2004.
