It's not so shocking to us that Jennifer Garner takes sexy selfies and sends them to hubby Ben Affleck ... I mean, a girl's gotta do what a girl's gotta do. BUT, the fact that she calls them "Polaroids" kinda blows us away!

Yes, that's an iPhone in her had in these pix we snapped Wednesday, but apparently she and Ben aren't using their cell phones to take pix of themselves (or of each other), they're using an ancient relic called a Polaroid camera, y'all.

"Polaroids! That's what we do at the Affleck house. We have a stack of sexy Polaroids!" Jen told Vanity Fair at the Toronto Film Festival, while promoting her new film Men, Women and Children.

The movie centers on the way social media and technology have changed relationships. The actress has spoken out about not getting cell phones for her kids, limiting their computer time, etc. But this recent revelation that she and Ben are complete Luddites is just ludicrous. You don't think she's actually joking, do you? Could she, would she be sending sexy cell phone selfies to Ben while he's shooting Batman in Michigan??? She better DAMN well be sending nude photos AND Facetiming some serious stuff if she wants to hold on to her man while he's away! Polaroid, shmolaroid!
