Jennifer Garner held nothing back during a recent appearance on the Ellen show. While the chat got off to a good start — Jennifer talked about dressing up for Halloween with her kids, Violet, Seraphina, and Samuel — it quickly turned into a hilarious discussion that husband Ben Affleck may not be super pumped about seeing on TV. Jennifer told Ellen DeGeneres all about Ben's aversion to his Tin Man costume (the brood went as Wizard of Oz characters last year) and went on to show a candid photo of her hubby in costume to the audience. When asked about a comment she made during her last visit to the show in September 2012, Jennifer fumbled while trying to clarify her quotes about Ben's "wonder sperm," saying, "Spermy has so far been held at bay." Jennifer's Ellen interview airs Friday, but you can watch a clip from the sit-down right now.
