Everyone loves to knock Justin Bieber, but how many actually get to do it to his face?

Standup comic Chris D’Elia brought the Bieb on stage last December at the Laugh Factory in Los Angeles and promptly went to work on him. But it was all in good fun—a request, in fact, from the Canadian idol, who’s a big fan of D’Elia. Bieber’s not alone. D’Elia’s fan base has been growing since he costarred on NBC’s Whitney for two seasons, before going on to lead the cast in Undateable, also on NBC.

The 34-year-old with the permanent 10 o’clock shadow may have started in acting, but he’s said what he enjoys more than anything else is standup. You can see him live at the Comedy MIX from Thursday through Saturday (June 19 to 21) fresh off a Monday-night appearance on Conan.
