Justin Bieber stands up for 'Bully,' lends a song to the doc's new ad campaign -- VIDEO

Justin Bieber just got a little dreamier. The Canadian singer has been vocal about his support for The Weinstein Company’s Bully for weeks now; on Twitter, he’s lauded the doc as “intense” and “powerful,” inspiring fans to go see the film for themselves.

Now TWC has announced that Bieber’s inspirational “Born to Be Somebody” will score a new TV spot for the film’s upcoming PG-13 release. The 30-second ad, which originally debuted on Fandango, will air nationally.

In a statement, Bieber thanked his fans, calling their dedication to great causes “one of the things I’m most proud of as an entertainer.” He also reiterated his support for the documentary: “I hope they see Bully with their friends and help start the conversation so we can end bullying,” he said.

By participating in Bully‘s campaign, Bieber joins fellow tween-friendly stars Cory Monteith and Naya Rivera. The Glee actors partnered with GLAAD and TWC in a pair of anti-bullying PSAs that premiered exclusively on EW.com.
