10 August, 2010 - Katy Perry only landed in Australia this morning, but already she’s making plans to party like a true blue Aussie.She Tweeted Ruby Rose on arrival looking for a party buddy, “@RubyRose1 she here! DM your cell! :)". Unfortunately Ruby is currently on the wagon so don’t expect any wild partying from her. “@katyperry Done, my modern day betty boop. X why did you bring the bad weather? And why come when I'm 20 days sober."
