Justin Bieber is proving he's not the only one in his world.

He brought his "My World" tour to Nashville's Bridgestone Arena and donated a portion of every ticket sale to Middle Tennessee flood relief. Promoter AEG Live matched the donation from the Aug. 11 show.

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.

Bieber says, "Music has been a part of my life for as long as I can remember, and you know Nashville, there's so much music history here."

Record flooding in May killed 22 people statewide and caused more than $2 billion in damage in Nashville alone.
