"I was at something recently and Diane Keaton was there and I got a little tongue tied," the 36-year-old actress admitted.
The Critics' Choice nominee also addressed her acclaimed new film, and why it seems to be resonating with audiences.
"It is actually full of unexpected hilarity, there's moments in the movie that you can't believe it, you just find yourself laughing," Williams said of the Kenneth Lonergan-directed family drama. "It's so much like life, these sort of good and bad things happen in concert with each other."
