Jason Merritt/Getty ImagesBack before he became the hunky A-lister we all now know him as, Ben Affleck was playing the son of a small-town football coach on a short-lived television show, working alongside Blake Lively's sister.
Wait...what?
Yes, you heard that right. Affleck may have had an on-screen romance with Blake in their 2010 film The Town, but nearly 20 years before that, he played Robyn Lively's brother on the 1993 TV series Against the Grain.
In fact, Blake's older sister took to Instagram to share the hilarious evidence.
Sharing a photo with hand-drawn arrows to point out Affleck and herself, Robyn explained: "Before #BenAffleck was hookin up with my cracked out sis @blakelively in #thetown he was just being my darling brother in a series called #againstthegrain."
She added, jokingly, "Wait this is all becoming way too incestuous for me #3degreesofbaconAffleck."
And speaking of #throwbacks, another lady from Affleck's past couldn't help but poke a little fun at him earlier this week, too.
While visiting Watch What Happens Live, Jennifer Lopez couldn't help but laugh when Andy Cohen mentioned the actor's enormous phoenix tattoo on his back.
"It's awful! What are you doing?" she said during the show's "Plead the Fifth" segment. "I mean, I would tell him that. I would tell him, 'What are you doing?' It has too many colors. His tattoos always have too many colors. They shouldn't be so colorful. You know what I mean? They should be cooler."
LOL! Check out J.Lo's full reaction in the video below.
