Justin Bieber's back on "Ellen" and this time, he's a security guard.
Well, not really. The singer, who has been quite the regular on "The Ellen Show," pulled a major prank on audience guests when he dressed up as a bearded security guard. Wearing a hat and sunglasses, Bieber was unrecognizable as he asked guests to perform sobriety tests and pretended not to know what an iPhone was.
Props on keeping a straight face, Biebs.
