The Hustlers star is seen caressing Affleck’s face in another shot as they stare into each other’s eyes.
Affleck also put on the moves as he was seen nuzzling J.Lo’s neck at the dinner table.
The Gone Girl star can also be seen whispering into Lopez’s ear during one point in the meal.
Exclusive video from the family gathering, which has been obtained by the New York Post, shows that J.Lo’s kids with ex-husband Marc Anthony – 13-year-olds Max and Emme – were also present for the occasion.
During the dinner, the twins made their way over to Affleck and Lopez to show them something on a smartphone.
It’s no surprise to see Affleck getting together with Lopez’s extended family since it’s been reported that the Oscar winner has her mother’s approval.
Last week, a source told People that Guadalupe Rodríguez is “thrilled” about her daughter’s rekindled romance.
“In the past, Jennifer’s mum and Ben were very close,” the insider said. “Guadalupe loved Ben. She was sad when they couldn’t work things out years ago.”
Affleck and Lopez, who were engaged back in 2002 but never walked down the aisle, first sparked rumours in April that they had reunited, Page Six exclusively reported.
Their romance began just weeks after J.Lo’s break-up with fiance Alex Rodriguez following rumours that A-Rod, 45, had cheated on her.
Since then, the couple have been doing their best to spend as much time as possible together.
In May, Bennifer took a trip to the ultra-exclusive Yellowstone Club in Montana and most recently rented a holiday home together in Miami.
Lopez is reportedly planning on relocating to Los Angeles full-time to be closer to Affleck.
