Natasha Leggero takes no prisoners in the upcoming Justin Bieber roast on Comedy Central. In this promo clip from Comedy Central’s Roast of Justin Bieber, the Last Comic Standing comedian tore into the evening’s Roast Master Kevin Hart. “Kevin Hart does all his own stunts,” Leggero starts. “He gets out of his own chair…he goes up on his wife.” Leggero took out Kevin Hart, Ludacris, Justin Bieber and Shaquille O’Neal in one awesome joke.
