Katy Perry puts 100 per cent into everything she does whether it's being a cock-tease, changing her clothes or going on a trolly dash round Claire's Accessories...

Everyone's still a bit baffled about how/why Katy Perry and Russell Brand are still together. Probably because they spend no more than five minutes together per month we'd say... Here's the singer taking some time out of her relentless album promo tour last night sporting some circa 2001 clip-in hair streaks (last seen on Kym Marsh we think).

Perry is incredibly hard working, knows her audience (smalls girls and all men), never actually tries to be edgy and seems nice (based on pic 3) allbeit very average looking in the face - if she wasn't a pop star she'd be the most well-tipped waitress at the Rain Forest Cafe with a second shift at Hooters. Russell Brand would've still shagged her.
