Tennessee rockers Paramore have been added to the bill for this year's iTunes Festival in London. 

The 'Still Into You' stars will perform at London's Roundhouse venue, which is hosting the month-long free live music series, on September 4 and fans can apply for tickets by going to the event's official website. 

Tweeting about the exciting news earlier today (June 19), the band told British fans: "Paramore is playing the @itunesfestival on Sept 4th! UK fans can get free tickets & everyone else can stream it."

Also joining the line up are 'Sex on Fire' hitmakers Kings of Leon (September 11) and Vampire Weekend (September 15). Previously confirmed headliners include Justin Timberlake, Jessie J, Thirty Seconds To Mars, Queens of the Stone Age, and Rizzle Kicks. 

Meanwhile, Paramore will tour the UK and Ireland in September with their first date taking place on the 2nd at Dublin's O2 venue. They will round up the run of shows with a headlining gig at London's Wembley Arena on September 27 and tickets are available now.
