Rihanna to perform free of cost for fans

London: R&B star Rihanna is set to play a free concert for revellers at a festival in Poland, a day after the event ends.

The `Umbrella` hitmaker will take to the stage 24 hours after the Open`er Festival in Gdynia officially finishes to perform a bonus set. Fans with a ticket to the four-day event will be permitted to return to the site to watch the 24-year-old singer`s gig for free, reported Daily Star. The Open`er Festival at Gdynia-Kosakowo airfield runs from July 3-6 and will feature headline sets from Blur, Kings of Leon, Arctic Monkeys, and Queens of the Stone Age. Rihanna will perform at the venue on July 7 as a nod to her recent seventh album Unapologetic, which she promoted with her 777 Tour, playing seven shows in seven countries over seven days. "Rihanna - yes, Rihanna! - will perform in Poland on 7.7.2013! The artist will give a special performance in Gdynia, the day after Open`er Festival, and the great news is you get to go to that show too if you have a full 4-day festival ticket," her representative said.
