Katy Perry was outside the ITV television studios in London, England last night, getting ready to appear on a show and she stopped to give her crazy fans a little love.

This is the first time I have seen a fan get their BlackBerry autographed.  Perhaps they came unprepared, or they just really wanted Katy’s scribble on their phone.

I can see it now, a Katy Perry cell phone case line, with her signature all over it.  Would it sell?  Of course it would. It’s Katy Perry.
