If you've seen Gone Girl, chances are you missed the big debut of Ben Affleck's member. We're not here to spoil anything, but will let you know you'll miss it if you blink.

And now his wife, Jennifer Garner, is here to tell you that what you probably missed is absolutely huuuuuuge.

During her Oct. 8 appearance on The Ellen DeGeneres Show, the 42-year-old beauty was quizzed about her hubby's, um, member by the hostess with the mostess.

After Ellen suggested it was a way to get more ratings, Jen agreed. "He's showing his penis. I think you're probably onto something."

She jokingly addressed the audience, "What I have to say is, 'You're welcome.' I just try to consider myself a charitable person and I wanted to give back. You give me so much, I wanted to give something back to all of you."

Aaaand then the TMI arrived.

"It wasn't a discussion, it was like, 'Hey, at work today [David] Fincher talked me into coming out of the shower.' And I was like, 'Oh, cool, well, I hope he had on a wide lens.'"

Don't you just love her even more? (And aren't you just that much more jealous of her?)
