The Leftovers star rode his sexy motorcycle to the set of Cake, then took off his sexy jacket and and hung out in Jen's sexy trailer.
OK, it was just a regular trailer, but Justin and Jen were in it, so it became sexy pretty quickly.
And speaking of pretty, it was a quick visit, so we wonder if Jen kept the scar makeup on. We bet a sensitive guy like Justin wouldn't mind!
Ch-ch-check out the pics (below) to see Mr. Theroux cruising through, just too cool for school and too sexy for… plexiglass? Whatevs, he's HOT! LOLz!
