Why bother with a cab or a bus when you can just jump on the back of your nearest pop star?!
We spotted pop star Mika giving Katy Perry a piggyback ride in London last night.  The singers were exiting the Serpentine Gallery summer party at Kensington Gardens in London when the camaraderie of being pop stars swelled up between the two of them and they collided into a drunken singer sandwich. Or something like that.

        

Katy Perry's outfit is a sensory overload!  We spotted the singer leaving the Howard Stern show in New York this afternoon wearing a multitude of patterns, colors and textures, but hey, only a slim few can pull that off!  Katy is up for a VMA at this year's awards for Best New Artist against Miley Cyrus, Taylor Swift, Jordin Sparks and Tokio Hotel.  Care to cast your vote?
