LOVE THIS! Katy Perry and hubby, Russell Brand took Katy's 90 year old grandma out in Vegas last night to celebrate her big bday. Check out the P.I.M.P. cane Granny's rockin'. BLING IT!!
In other K.P. news, Katy will be performing at the Grammy's next month and is nominated for four awards. GOOD LUCK, Pussycat!
