Alexandra Burke says that she's "so excited" for fans to see the music video for her new single 'Don't Let Me Start Without You', which she filmed with rapper Laza recently.

Over 150 extras were used in the video, forcing streets to be closed off while they filmed scenes for it. Burke wrote on her Twitter page, "Can't wait4 u guys2 see this video!! I'm having so much fun! Shooting my video with my boy (Laza)!!! Watch this space for him people ! He's gonna bloow up!!!"

Reacting to news that the song had leaked on to the internet weeks ahead of its release, she said, "The single leaked online way before I was ready to put it out. I was annoyed at first but it created a lot of hype."

Burke is set to release 'Don't Let Me Start Without You' later in August.
