The Stronger hitmaker, who is scheduled to wed fiancee Kim Kardashian this weekend (24May14), will return to the Benjamin Franklin Parkway venue over America's Labor Day weekend to entertain audiences, two years after he joined Jay Z as a special guest onstage at the inaugural two-day event in 2012.
Kings of Leon, Pharrell Williams, dance DJ Tiesto, The National, rap veterans De La Soul, Steve Aoki and J. Cole will also be part of the 2014 line-up.
This year's bash will also be celebrated simultaneously in Los Angeles for the first time. Performers for the west coast show are due to be unveiled later on Thursday (22May14).
Jay Z's superstar wife Beyonce and Nine Inch Nails topped the bill at last year's (13) festivities in Philadelphia.
