Inside Jennifer Lopez, Ben Affleck's PDA-Filled Dinner Date; Are They Back Together?

Jennifer Lopez and Ben Affleck were not shy about showing their affection for each other in their most recent outing, a report says.

Lopez and Affleck were spotted enjoying dinner at Wolfgang Puck's restaurant Merois on the rooftop of the Pendry hotel in West Hollywood, California, Monday. Lopez's manager Benny Medina and movie producer Elaine Goldsmith-Thomas accompanied the pair, E! News reported. According to unnamed eyewitnesses, Lopez and Affleck were very affectionate with each other throughout the meal.

"Ben had his arm around Jennifer at dinner and they weren't shy about being affectionate," one eyewitness told the outlet. "He looked great and seemed very happy. She also looked happy and kept leaning into him."

The singer and actor reportedly cuddled at the table and "looked very comfortable and relaxed together," the source said.

The onlooker also noticed that Affleck appeared to have no problem blending in with Lopez and her pals.

"He mixed in well with her friends and seemed very comfortable talking to them and making conversation," the eyewitness continued. "They all had a lot of laughs and a great time."

After their dinner, Lopez and Affleck held hands as they walked out of the restaurant and kept close, according to the source, who added that the singer rested her head on his shoulder at one point.

It remains unknown if Lopez and Affleck are officially back together. However, an anonymous source close to the "Hustlers" star told the outlet that she's "crazy" about Affleck.

"He spoils her with love and is very witty and charming," the insider said of Affleck. "He's a man's man, and she finds him so attractive and strong. She's in it for the long term and sees her future with him."

Another unnamed source close to Lopez said the "Justice League" star is "really making a huge effort" to make things work between them despite their busy schedules. Last week, they spent a few days in Miami together, after their Montana getaway during the Mother's Day weekend.

"J.Lo thinks Ben has really stepped up and loves this version of him," the insider continued. "It's comforting to her and she is smitten."

But while Affleck and Lopez, who were engaged between 2002 and 2004, have yet to officially confirm that they've rekindled their romance, one anonymous source told People they were already "slowly starting to talk about the future."

"This is not a casual relationship. They are taking it seriously and want it to be long-lasting," the source added.
