Canadian teen singing sensation Justin Bieber says he opposes bullying in an It Gets Better video.

The 16-year-old American Music Award-winning singer's video premiered Monday on the Ellen DeGeneres Show.

Bieber keeps his message short and to the point in his 20-second clip.

“Hey guys, I'm Justin Bieber. I just wanted to say there's nothing cool about being a bully. And if you're getting bullied, make sure to tell someone and, you know, it gets better. And if you're a bystander, make sure to step in and, you know, help out,” he says while wearing a black T-shirt and black baseball cap worn backwards.

On the show, Bieber said that even he has been bullied.

“Everybody goes through bullying. Everybody has, even me. On my YouTube page, there are so many haters.”

The It Gets Better Project is a collection of inspiring videos that urge troubled gay teens considering suicide to get help.

Other celebrities who have added their voices to the collection include singer Adam Lambert, Max Adler, who plays a bully on Glee, actor and gay dad Neil Patrick Harris and singer Ke$ha.
