• Jennifer Lopez and Ben Affleck spent several days together in Montana
  • The exes spent Mother's Day weekend in Big Sky with just the two of them
  • The "On the Floor" singer was reportedly happy with their quick getaway together

Jennifer Lopez and Ben Affleck were together on Mother's Day weekend, according to a report.

The "On The Floor" singer and "Gone Girl" star spent the weekend together in Big Sky, Montana, a source told Us Weekly. They were reportedly out on vacation, and it was just the two of them.

"Ben and Jen spent several days together in Montana," the source told the outlet Monday. "It was just the two of them on vacation together. Big Sky is a special place to Ben."

The source added that Lopez and Affleck "looked very happy together" during their getaway. Daily Mail also obtained photos of them riding an SUV together. In one picture, Affleck is driving the car while Lopez is seated beside him.

Another insider confirmed to People that the exes spent several days together in Montana.

"[Jennifer] spent several days with Ben out of town. They have a strong connection. It's all been quick and intense, but Jennifer is happy," the source said.

Affleck and Lopez both participated in the Vax Live concert in Los Angeles that was filmed on May 2. The "Maid in Manhattan" star put on a show-stopping performance in her trademark skimpy outfit. Meanwhile, the "Batman" star took the stage with Jimmy Kimmel.

Lopez celebrated Mother's Day by sharing photos of herself with her 13-year-old twins Max and Emme and mom, Guadalupe Rodriguez, on Instagram. Meanwhile, Affleck remembered his ex-wife, Jennifer Garner, by sharing candid photos of the "Yes Day" star cuddling their children on social media.

"So happy to share these kids with you. Luckiest parents in the world. Thanks for all the good you do," Affleck wrote. "Happy Mother's Day. Love, their Dad."

Affleck and Lopez's sighting is not surprising as multiple sources said last month that they have been seeing each other. The formerly engaged couple was reportedly spotted at Lopez's home following their respective splits.

Affleck and Ana de Armas separated in January after almost a year of dating. Meanwhile, Lopez and Alex Rodriguez called off their engagement last month saying they were better off as friends.

However, several sources said that despite spending time together, Lopez and Affleck are just friends.

"They are friends … they’ve never not been," a source told Page Six.

"They are just friends," another source told E! News.
