London: Pop star Jessie J has apologised to fans after bowing out of an upcoming music festival in Switzerland.
The `Price Tag` hitmaker was due to play the Heitere Open Air event in Zofingen, alongside acts including Rita Ora, Empire of the Sun, Pitbull and Public Enemy, reported Contactmusic.
But now the 25-year-old singer has dropped out of the event with less than a week to go before her scheduled slot on August 9.
Taking to her Twitter page, Jessie said, "Heartbeats (fans), sorry I have to pull out of Fridays festival due to recording/promo commitments in the US. So gutted not see you!"
