Katy Perry Is in Awe of Husband Russell's Past -- Potent Quotables

"If I have a hangover, I look at [husband, Russell Brand] and say, 'How the f--- did you do heroin every day, when I can't even have three glasses of wine and not want to ever drink again?' I'm so happy he lived, of course." -- Katy Perry

Katy Perry reveals in an interview with Rolling Stone that she struggles with post-party hangovers just like her alter-ego in her 'Last Friday Night (T.G.I.F.)' video -- unlike her once-hard partying hubby Russell Brand.
