Rita Ora axed her concert in Philadelphia, Pennsylvania on Thursday night (20Dec12) after reportedly falling ill.
The R.I.P. hitmaker's show at the Trocadero Theatre was originally due to take place in October (12), but the date was rescheduled as a result of superstorm Sandy, which caused devastation across the East Coast.
Ora was expected to hit the stage with support from rapper Iggy Azalea this week, but the gig was scrapped at late notice.
In a Twitter.com post on Thursday, she wrote, "I am so sorry Philly for cancelling tonight. I will be back next year..and make it up to (you) I promise I love you!"
The singer failed to give a reason for the cancellation, but a message on ticketing website Ticketfly.com blamed it on "illness".
