Looks like Katy Perry's having a ball in Australia. Fresh from hosting the Teen Choice Awards with the Glee guys, she played in Melbourne last night and appeared on Sunrise this morning. But it looks like she's still had time for a spot of shopping — she was spotted buying up big at Wheels & Dollbaby — and to meet some fans, some of whom were more dedicated than others. Katy tweeted this shot, saying "This kinda dedication deserves a twit pic... I'm on her nails!!!" What do you think, is a little nail homage cool 'n cute or totally tragic?
