PHOTOS: Usher performs with crutches at World Bank event.

No one expected to see Usher on stage performing anytime soon as a result of his recent foot surgery that has left him using crutches for the past 3 weeks.

The 36-year-old singer, however, defied all odds and went ahead to perform with ‘One Leg’ at the World Bank Event event that held in Washington DC on Saturday, April 18, 2015.

 Usher was joined on stage by Common while other super stars like Gwen Stephani, D’banj, Fally Ipupa and others performed at the event as well....
