|Katy's on Stage Style|
As for on stage, Katy appeared to take a dig at her now ex hubbie, Russell Brand as she debuted her new single "Part of Me". As if singing “You can keep the diamond ring. It don’t mean nothing anyway. In fact you can keep everything. Yeah, yeah, except for me.” wasn't bad enough for Mr Brand, how hot did Katy look in her skin tight PVC number!
