Pop star Katy Perry will be bringing some exciting extras to her California Dreams Tour, including glow in the dark cotton candy. 

The sweet-toothed singer took to her Twitter page yesterday (January 25) and wrote:

"PREPARE FOR YOUR COTTON CANDY TO GLOW ON THE #CALIFORNIADREAMSTOUR, NO JOKE! LOLZ."

She then posted a link to a company that specializes in making candyfloss that sits on illuminated sticks. Perry, 26, will feature the unusual treat on the U.S leg of her forthcoming tour.

In the last five minutes (January 26), she tweeted a link to a special video that has been created by The Grammy Awards to celebrate her achievements and support her nominations. Watch it here:
