If you need some conversation starters, Justin just announced his first-ever headlining tour, which will hit over 40 cities in the U.S. and Canada. He's also performing on The View twice, which has never been done by any other artist.
You could also ask him about his 'Baby' video or find out what's in store for the video of his brand-new single, 'U Smile.' It was just released on Tuesday, so he'll have plenty to say. Of course, Justin's sophomore album, 'My World 2.0' is coming out on March 23, so you can ask him all sorts of questions about that, too.
