And with that, the shellacking of the 21-year-old pop star began, starting with a video montage that included all of Bieber's embarrassing legal woes and continuing with a tidal wave of cracks about the singer's pre-pubescent fanbase, his goofy songs and all those appearances on Ellen.
And that was just when Ludacris, comedian Natasha Legerro and Shaquille O'Neal took the stage Saturday on the Sony lot outside of Hollywood, the site of the Bieber roast taping.
How exactly does a panel of African-American rappers, comedians, a ex-basketball player and a professional homemaker roast a guy like Bieber? With gleeful abandon and lots of bleeps by the standards and practices department. Besides countless f-bombs and references to female sex organs, there were nine Bill Cosby jokes, three Bruce Jenner yuks and way too many Selena Gomez references to count. Ron Burgundy – a.k.a. Will Ferrell – made a surprise appearance, and first-time roaster Martha Stewart absolutely killed.
All the while, a purple suit-wearing Bieber either slapped his knee while busting a gut or sat quietly, looking like a frightened deer.
"Damn, you guys were brutal," Bieber said at the end of the roast. "This was supposed to be a birthday present. When people ask me what I got for my 21st birthday, I'll tell them I got my d--- kicked in. I should have known."
And then, in an expected serious turn, Bieber looked straight into the camera and apologized for his past behavior.
"I lost some of my best qualities," he said. "I'm looking forward to being someone to be proud of. Someone close to me once said how you rise from a fall is how you are truly defined as a man."
