Justin Bieber + Friends: Ryan Seacrest

Ryan Seacrest has been described as the hardest working man in show business. We don't disagree with that, but we think at this point Justin Bieber gives the host with the most a run for his money.

The duo get along great, and Biebs often breaks news and drops in on Seacrest's radio show. And sometimes, like in this shot, they take trips to Disney together. Cute!
