Justin Bieber

Teen pop star Justin Bieber might be young, but he knows a thing or two about giving back. He brought his 'My World' tour to Nashville's Bridgestone Arena Wednesday and donated a portion of every ticket sale to Middle Tennessee flood relief. Concert promoter AEG Live matched the donation. Together with proceeds from last month's show featuring Miranda Cosgrove and Kris Allen at a smaller venue, Bieber presented a check for nearly $33,000 to The Community Foundation of Middle Tennessee.
