We hear there may be fireworks between Katy Perry and her ex-husband, Russell Brand! Despite their shocking and sudden divorce, Radaronline reports Katy has been looking to Russell for advice over her split from John! Sources tell the site, "Katy reached out to him after she split with John. He flattered her with compliments and just listened to her every word." Some say Katy's relationship with Russell was to blame for her split from John in the first place-- he was sick of constantly being compared to the actor.
