We spotted Katy Perry in yet another unusual outfit as she excited London’s Koko club late last night.  The singer performed on stage earlier in the evening as part of her of her European tour. 

Katy has responded to the rumors that she and Benji Madden are hooking up (after being seen together in Las Vegas on Valentine’s Day).  She writes on her blog, "It’s two pseudo famous people sitting next to each other… doesn’t mean we were bumping uglies! You know I don’t just do that with anyone! That’s just how the media works, as you can tell. I was there celebrating a really fun show and a boozy Valentine’s with all my good friends. We were like a group of 25."

She adds that her main squeeze these days is her cat, "’Benji is a nice young fellow, but my heart really belongs to Kitty Purry"
