The rapper will headline the event at London's Olympic Park on Saturday night, but he showed up a day early to perform with Timberlake at the end of the singer's set, which included hits such as "Cry Me a River," "Senorita" and "Mirrors," as well as a cover of of INXS anthem "Need You Tonight."
Timberlake closed his headlining set with "SexyBack" after a brief performance with his pal Jay-Z, while the singer/actor's wife Jessica Biel watched from the side of the stage, along with Rita Ora, Frank Ocean and Snoop Dogg -- also known as Snoop Lion.
The Wireless Festival's first night featured sets from Snoop Dogg and Ocean, as well as John Legend and Miguel. Jay-Z and Timberlake will be back onstage together at the event on Sunday, when they wrap up the festival as headliners.
