This is Actress Katie Holmes exhibiting a great example of a "Lizard Tongue". Depending on its context and other body language signals seen with it, a tongue-jut can have several meanings: I got caught, I've been bad, I got away with something, excitement or I did something silly (Navarro). It can also indicate self-deprecating humor depending on the other nonverbals with which it is clustered. The Lizard Tongue is not to be confused with the "Tongue in Cheek" nonverbal, wherein the tongue is pushed to one side, against the inside of the cheek, and is often not visible. When you see the tongue-jut - take note as it is often seen with a "serious face" and in business or other formal settings.
