The Emeli Sandé concert at the Marquee has been cancelled just over a week before the singer was due to perform.
Aiken Promotions has yet to announce officially that the gig has been cancelled but Ticketmaster has removed ticket sales from its website for her Cork show on July 10, along with her scheduled Edinburgh show on July 13.
No reason has been given for the cancellations and no details on how those who have already purchased tickets can claim a refund have been announced.
Cork-born singer-songwriter Stephanie Rainey had been advertised as the support act for Ms Sandé who has enjoyed a remarkable series of success since her debut album Our Version of Events in 2012.
She is currently promoting her Long Live the Angels album and will embark on a UK and Ireland tour later this year.
The singer is set to play Belfast in August and Dublin in October.
Live at the Marquee promoter Peter Aiken told the Evening Echo last month that tickets for all gigs at the venue were selling well.
