Katy Perry turned the stage at Los Angeles' Nokia Theatre last night (August 6) into a sweet heaven, as her stage set included giant gingerbread men, gummie bears and girls in cupcake dresses.

Perry, who is playing three sell-out shows in L.A., wowed the crowd in a silver lame bikini and blue 'Smurf'-style wig before turning into a giant Hershey's 'kiss' chocolate.

The California Dreams world tour started on February 20 in Lisbon and takes in over 100 concerts. It's scheduled to see Perry perform her first ever gigs in South America and will end in L.A.'s Staples Center on November 22d.

The UK leg of the tour commences on October 12 in Sheffield, and will see her play London, Liverpool, Cardiff, Belfast, Birmingham, Newcaster, Aberdeen, Manchester, Glasgow, Nottingham and Dublin.
