Pop superstar Katy Perry has scored her third million-selling album in the US with her latest record, Prism.
In just 11 weeks, the 29-year-old 'Roar' hitmaker has surpassed the one million sales mark, according to data from Nielsen SoundScan, reported Ace Showbiz.
The feat comes after her debut album, 2008's One of the Boys, and her follow-up effort, 2010's Teenage Dream, hit the milestone figure after 20 weeks.
