Jay-Z and Justin Timberlake are set to embark on their co-headlining “Legends of the Summer” tour, kicking off this Wednesday in Toronto, Canada. The two megastars used the Yahoo! Wireless Festival stage in London, England on Sunday night as a warmup to their North American trek.

Performing a 3-hour joint set, JZ and JT rocked Queen Elizabeth Olympic Park with hits in their solo catalogues plus their two collaborations “Holy Grail” and “Suit & Tie.” Together, they performed over 40 songs and special guest Rihanna joined Jay-Z for “Run This Town.” 2 Chainz and Gwyneth Paltrow were among the attendees spotted taking in the show.
