Alexandra Burke has posted a new blog entry, in which she apologises to her fans for the delay of her forthcoming new single.

The former X Factor winner was due to release her sophomore album's lead single this week (beginning September 12), but explained that some unexpected "exciting things" have caused a slight setback. She wrote:

"To all my supporters out there.. Firstly again. Thank you for you patience. I am so so sorry for telling you guys that a single would be serviced to radio this week, that was the plan but weve decided to take a tiny bit more time as some exciting things have come up that we are looking at and RCA want to make sure everything is perfect. So please bare with us."

"I promise you all it will be worth the wait. When I get a date that is confirmed for the single to be serviced to radio I will inform you all once I know it is CONFIRMED!!"

She hasn't yet revealed details of these last minute tweaks, but you can watch her talk about her upcoming new record here:
