Justin Bieber Breaks Twitter

The servers that control Twitter went down temporarily last night, and anyone familiar with the work of Justin Bieber understood why. The teenage superstar surprised his Madison Square Garden audience with a duet of “Overboard” with Miley Cyrus, and millions of tweens took to the internet to discuss that intrigue. After introducing Cyrus with his single “Never Say Never,” a crew of additional surprise guests paraded across the stage, including Sean Kingston, Usher (who left the stage after giving Bieber a big hug), and Ludacris, who closed the show. Like the ghost of boy bands past, Boyz II Men were on hand for “U Smile,” and a Mrs. Bieber-dedicated “On Bended Knee.” The live footage was filmed for Bieber’s upcoming 3D biopic, a film chronicling his (short) life story, to be directed by Jon Chu and set for release on February 11, 2011.
