R&B singer Usher is busy promoting his latest album Raymond v. Raymond overseas and was spotted out signing autographs earlier today (Fri. Jun 4) as he left the Mayfair Hotel in London where he’s staying while he’s in town. UK shutterbugs also caught the entertainer leaving BBC Radio One studios in London yesterday (Thu. Jun 3) after doing some interviews.

In related news, Usher’s worldwide smash hit single “OMG” spends its 4th week on top of the Billboard Hot 100 singles chart, keeping Katy Perry, B.o.B and Ke$ha right up under him (in that order) on the list.
