Oops.

Mel Gibson has worked hard to try and repair his image after a regrettable 2006 DUI arrest, but did an on-camera swear word send the whole thing unraveling?

Gibson’s slip-up occured on the WGN News at Noon, based out of Chicago. Anchor Dean Richards asked Gibson about if he felt the public had gotten past the negativity stemming from the ’06 arrest — and subsequent revelations about said arrest — and Gibson said that, hey, it’s been four years, so maybe we can focus on other stuff.

(I mean, yeah, that’s always going to be hanging in the air about Mel, but this is a noon-time fluff piece, isn’t it?)

However, Mel wasn’t thinking about other stuff, and decided to mutter something under his breath. Understandable, to be sure, but THE CAMERA’S STILL ON!
