Justin Timberlake will be flying to London this September for Apple's iTunes Festival free concert series. The "Suit & Tie" singer will be among the 60 plus performers who will be spread throughout September to play at London's Roundhouse performing arts and concerts venue for the annual music fest.

Another top act in the line-up is British dance-pop star Jessie J who teased fans that she would be "back with new music, a new look and a party you're all invited to." Other confirmed performers in the line-up revealed on Thursday include rock bands Queens of the Stone Age and 30 Seconds to Mars, French alternative rock band Phoenix, Scottish alternative rock band Primal Scream, British artist Jake Bugg, and Hawaiian-born folk-rock singer Jack Johnson.

"This year's iTunes Festival is the best ever with an incredible lineup of global superstars and stellar emerging artists," exclaimed Apple's senior vice president of Internet software and services Eddy Cue. "Music fans around the world are going to love watching this incredible month of music, whether in London at the Roundhouse or on their own device."

Launched in 2007, the annual iTunes festival has already featured 370 plus acts who have played for more than 370,000 live spectators and millions more on TV and online. Past performers include Paul McCartney, the late Amy Winehouse, Adele, Coldplay, Dave Grohl's Foo Fighters, Alicia Keys, the legendary Paul Simon and Liam Gallagher's former band Oasis.
