Katy Perry asks fans for help

Katy Perry has been asking her fans to choose which single she'll release next from the Teenage Dream album.

California Gurls, Teenage Dream and Firework have already proved massive hits but Katy has asked her Twitter followers for advice what should be next.

She tweeted: "PEOPLE u are the reason why I'm here, SO what song off of TEENAGE DREAM do u want to blow up NEXT?! Put a # next to the song YOU want!"

Later she wrote: "Thanks for all your great suggestions for the next single today! Your voice has been heard! We're on the same page..."

Among those who had their say was Perez Hilton tweeting his love for "Peacock."

The single will be released early in the new year.
