Songstress Alexandra Burke has revealed that her forthcoming 6-show residency at the Royal Albert Hall in London (June 2013) has been postponed due to 'overwhelming demand'.

Tweeting about the disappointing news this afternoon (May 16), the 'Broken Heels' hitmaker apologised for letting people down: "Hi, I'm afraid we're postponing the Royal Albert Hall shows until later in the year. Sorry for any disappointment. I'll tweet the statement."

Burke was supposed to play a run of dates at the venue's Elgar Room, where she was set to perform the soundtrack to 1972 Billie Holiday biopic 'Lady Sings The Blues', in which Diana Ross played the singer, but an official statement confirms that the dates are no longer going ahead:

"Due to an overwhelming demand for tickets, Alexandra Burke has decided to postpone her June 'Lady Sings The Blues' concerts and re-schedule the performances for later this year, at additional venues. Tickets for the six dates at the Royal Albert Hall's Elgar Room sold out within hours, with many fans disappointed, so these new dates, to be announced soon, will allow more fans to see and enjoy the shows."
