No, they're filming scenes for Ben's upcoming movie The Secret Life Of Walter Mitty!
Ch-ch-check out the pics (below) to see the two HIGHlarious stars hard at work! Oh, bad phrasing! LOLz!
The movie, about a timid editor who stumbles onto an adventure, has already wrapped principal photography. Ben is just doing a few reshoots to get it perfect.
Or maybe he just wanted to see Kristen again! LOLz!
