Ben Affleck "could not keep his hands off" Jennifer Lopez at their brunch on Saturday, a source exclusively told Page Six.
The "Argo" director wanted to meet his estranged wife at the Beverly Hills Hotel to show that they're "friends," and get their pics taken.
But he wound up not being able to keep his hands off his ex, sources exclusively told us.
The estranged couple was having brunch with their children at the famed Polo Lounge in Beverly Hills, Calif., on Saturday -- and that the stars were seen "holding hands and kissing."
A source tells us it was the "Justice League" star's idea for the former pair to meet at the high-profile spot in hopes of getting their pic snapped.
But Affleck apparently wasn't counting on finding the "On The Floor" singer so irresistible in person, says our source.
"Once they were together, he could not keep his hands off," our source said.
The insider added, "They have always had a lot of sexual chemistry. That was not planned. They are still attracted to one another."
"It was Ben Affleck's idea to meet there," the insider said. "He wanted to show that they are friendly exes."
"He wanted those photos," the source explains. "You go there when you want to be seen. Paparazzi hang out there."
The pair were also photographed having a seemingly intense conversation in a car outside the hotel.
Two of Affleck's children, Seraphina, 15, and Samuel, 12 -- and Lopez's twins, Emme and Max, 16 -- are close and sat at a different table during the family brunch outing.
But reports said that Bennifer's PDA-filled reunion doesn't mean a reconciliation. A source told People: "[Lopez is] trying to be friendly with Ben. They are still moving forward with the divorce though."
At the weekend brunch, Lopez perhaps symbolically wore her engagement ring on her pinky finger, and a "Jennifer" ring on her wedding finger.
They reportedly don't have a prenup.
"A divorce is never easy, but Jennifer doesn't want to be selfish about it," a source told People. "The kids always got along and have fun together. It makes her happy seeing the kids happy together. Happy kids are her priority."
Lopez was photographed smiling on Sunday as she arrived at a friend's house in LA, the day after the brunch meeting.
The hotel has a long history of being a celebrity favorite. Stars recently spotted there include Meghan Markle and Prince Harry, Oprah Winfrey and Jay-Z and Beyoncé.
