The popstar was due to play the Odyssey Arena later this year, following two sold out shows there this week.
But a spokesman for Aiken Promotions said that due to a scheduling review of the full autumn/winter tour of 2009, the current dates could not be released for sale until all of this is finalised.
He said: “The new on sale date for the November shows will be advised as soon as possible.
“Aiken Promotions would like to apologise for any inconvenience caused.”
The spokesman said that the Belfast show, and a Dublin O2 one, would still go ahead but that the dates had to be sorted out.
Meanwhile, Beyonce was seen splashing the cash on designer dresses in a top Dublin boutique earlier this week.
And despite being hailed as a curvy icon, in reality she takes a tiny size 8 when it comes to her sexy stage dresses.
She spent several thousand euros in upmarket store Chica in the Westbury Mall during a shopping trip with her mum Tina. She spent nearly an hour choosing a range of jewellery and designer gowns.
