Diane Keaton totally dropped the F-Bomb on Good Morning America! And they didn't even bleep it.

Keaton was being interviewed by Diane Sawyer, presumably about her new movie Mad Money. Sawyer is about to pose a question when Diane Keaton stops and compliments her on her lips (which are quite nice, I must say). Keaton laments that she doesn't have such nice lips cause if she did, she wouldn't have to work so damn hard on her "f*cking personality."

This is why I "heart" Diane Keaton. Of the two Dianes, clearly Keaton has the personality. She doesn't have to work on it.
