Justin Bieber Rewards Bullied Boy

You may not know the name Casey Heynes, but you'd probably recognize the 16-year-old's image. He's the Australian boy who became famous for defending himself against the bullies who were attacking him. A cell phone video of the incident quickly went viral and has been seen by millions around the world. This week, Casey got some sweet revenge, when his pop idol -- 17-year-old Justin Bieber, who's spoken out against bullying in the past -- flew Casey and his family to his concert in Melbourne, and even brought the 10th grader out on stage during the show, where he received cheers from the crowd.

Justin first met with Casey backstage prior to the show and in front of cameras for the newsmagazine show "A Current Affair."

"It shows everybody else that you have to stand up for yourself and you can't just take it." Justin told Casey. "The first thing you do is ...go tell someone. You can't always hit back, but sometimes you have to. So, I think that was important for you, especially in that situation. So, I'm proud of you. And so many other people are proud of you."

The Biebs himself was the victim of a bit of bullying recently when he was pelted with eggs onstage during his show in Sydney, Australia. Justin, however, refused to get rattled and kept going with his routine. The culprit was later arrested. Take that, bullies!
