Swimming with sharks..would you try it??

It definitely takes some courage to do it, and Justin Bieber stepped up to the task this week. A few days ago, he went to an aquarium to film some scenes for part of his Believe tour.

Justin didn't really have a good time shooting it, but at least he wasn't alone in the water - he was joined by some synchronized swimmers. Here's what he said about it:

"I was so scared. I hate sharks. It took, like, an hour for me to even jump in the water. Being with the ladies under there kind of made it a lot better."
