Over the past few years, increasing amount of celebrities have been turning to Twitter to give themselves a voice and self-publicise.

So when it came to Halloween, what better way for the stars to show off their creativity than to upload their costumes on the micro-blogging site.

Celebrities from the A-list to the Z-list couldn't wait to show off their handiwork as they prepared to celebrate the spooky holiday.
