Jennifer Lopez and Ben Affleck are already acting like an old married couple ... because they're already doing the thing that seems inevitable with time -- wearing matching outfits!
Ben and Jen were leaving the Hotel Bel-Air in L.A. Wednesday, after having lunch with her dad, David, and her kids Max and Emme.
Check out the photos ... they're both wearing tan-colored jackets. Maybe that's not a big deal, but it's the start of a relationship that has been cemented for a while.
J Lo and Ben have been spending lots and lots of time together, on both coasts and in other countries over the last 6 months. TMZ broke the story ... they're on the hunt in L.A. for a house together where, presumably, they will blend the 2 families.
As for marriage ... no word yet, but it wouldn't shock anyone in 2022.
