Bieber is pictured meeting fellow LD Communications client Mick Jagger at the Vanity Fair Oscar Party. LD was awarded the AEG Live account following a competitive pitch.
In the run-up to his tour, Bieber hit the news last week when a lock of his hair fetched £25,000 on the auction site eBay, with the proceeds going straight to charity.
Ellen Degeneres conducted the auction after Bieber presented it to her on her television show. The proceeds of the auction will go to the Gentle Barn Foundation – an animal rescue charity.
