Ben Affleck Jets Off With J Lo & Kids To Celebrate 50th Birthday

Ben Affleck has a tendency to turn himself into hilarious memes -- and as he jets off with Jennifer Lopez and their kids to celebrate his birthday ... he seems to be reprising a classic.

The newlyweds boarded a private plane Saturday at the Van Nuys Airport in L.A. with some of their kids in tow, it seems. We recognize two of BA's children here, but it's unclear if Jen's young ones are already inside or even there at all. In any case, this trip is a family affair.
