The lovebirds — who rekindled their old romance earlier this year — were photographed taking their kiddos to an afternoon movie showing at the Regency Village Theatre in Westwood, Calif., on Saturday, December 4. The blended family reportedly saw Paul Thomas Anderson's new film Licorice Pizza.
Affleck, 49, and Lopez, 52, were joined by the Gone Girl actor's son Samuel, 9, and daughter Seraphina, 12, along with J.Lo's twins Max and Emme, 13 — who she shares with ex-husband Marc Anthony.
In addition to his younger two kids, Affleck also shares 16-year-old daughter Violet with his ex-wife Jennifer Garner.
The on-again lovers appear to be working on blending their family as they head into the holiday season. Last month, a source spilled to OK! that Affleck plans to spend the holidays with both Jens for the sake of keeping their families together on Christmas.
"Christmas is all about the kids," the source explained. "Despite being polar opposites, Jennifer Garner and Jennifer Lopez have bonded over the children."
"It might sound strange to spend the holidays with your ex-husband's new girlfriend, but Jennifer [Garner] doesn't care what other people think," the insider insisted.
OK! previously reported the 13 Going on 30 actress found "common ground" with Lopez after spending time with their children together.
“Once it was clear that Ben and Lopez were serious about getting back together, Jennifer reached out," an insider said at the time. "When you have children with an ex and that person starts dating again, all three of you are linked together like it or not. Jennifer was determined to make sure that she had a relationship with J. Lo, if for nothing else, so that things were not awkward for her kids."
Meanwhile, Christmas won't be the first holiday Affleck and the Selena actress' kids spend together, as the kiddos trick-or-treated as one big happy family during Halloween.
