Dax Shepard Is a Smitten Kitten

Dax and Kristen sittin' in a seat... h-u-g-g-i-n-g!

The happy acting couple were spotted snuggling on the set of When In Rome -- in which they both star -- on Wednesday in New York Upper East Side.

Just look at how captured Dax Shepard is with his lady love Kristen Bell!

Watch out, Kristen: Dax has the googly eyes! Promise us you won't break his heart. We don't want to be the ones to scrape its tattered remnants off 78th street.

Co-stars Will Arnett and Josh Duhamel are also spotted in the mix.
