Putting on one of the hottest shows of the summer, Rihanna took the stage at the Yahoo Wireless Festival on Sunday evening (July 14).
The We Found Love songstress was joined by Jay-Z and Justin Timberlake for the grand finale performance at the Queen Elizabeth Olympic Park in Stratford, East London, and the packed audience went wild.
