Happy 21st Birthday, Justin Bieber ! It’s been an eventful past couple of years for the pop singer, to say the least. Which is why Comedy Central ‘s Roast of Justin Bieber will be one for the books. As an added bonus, comedian and close pal, Kevin Hart , has agreed to host. Hart told Ryan Seacrest last month, “He’s 100 percent nervous. It’s not even a half-question. He’s like, ‘Hey so Kev, you’re going to take it easy, right?’ And I said, ‘Absolutely not.” You can watch the Roast of Justin Bieber on Comedy Central on Mar. 30.
