Frank Ocean - Frank Ocean Cancels Summer Shows

The singer was due to play a number of huge gigs over the next few weeks, including an appearance at Britain's V Festival next weekend (18-19Aug12), Pukkelpop in Belgium and Bestival on the U.K.'s Isle of Wight.

He also scrapped his support slot with Coldplay on the band's upcoming European tour, which is due to kick off in Copenhagen, Denmark at the end of the month (28Aug12).

Ocean apologised to fans in a short statement, saying, "Let me start by saying I feel like an a**hole right now, but a tough decision had to be made in regard to my schedule over the next few months.

"The casualties of that decision include my appearances at upcoming festivals in Europe and my opening slot on the European leg of the Coldplay world tour. Sorry as f**k, I'll be back if you (sic) have me."

Ocean has not given a reason for the cancellations, but the news comes just a day after he scrapped an appearance at Sweden's Way out West festival on Saturday (11Aug12).

The star also cut short a show at Norway's Oya Festival on Thursday (09Aug12) - he left the stage after four songs citing vocal problems. A statement posted on the festival's official website, reads, "Unfortunately, Frank Ocean had to cancel his afternoon concert after just 15 minutes due to acute problems with his voice. We deeply apologise for the inconvenience this may have caused."
