How did Rebel Wilson spend her evening on December 15? Hanging out in London with a cold-blooded killer! Well, not really—Aaron Tveit is as sweet as they come—but in the new Menier Chocolate Factory production of Assassins, he’s unleashing his dangerous side, playing real-life assassin John Wilkes Booth. After the show, Wilson and Tveit (and his awesome new ‘stache) snapped this sweet photo by Broadway.com photographer Bruce Glikas. See the stars collide, then catch Assassins through March 7 at London’s Menier Chocolate Factory!
