PICS: Zachary Quinto, Shirtless and Filthy

By: Brandon Voss

Zachary Quinto is a dirty, dirty boy.

Reprising his iconic role as Commander Spock in Star Trek Into Darkness, in theaters May 17, the out summer movie hunk posed for another wild photo shoot with Tyler Shields, the celebrity shutterbug who doused the actor in milk for an infamous 2009 video portrait.

Quinto kept it cleaner when he recently spoke to Out about his bromance with costar Chris Pine, the magazine's new cover boy.
