Jessie J - Do It Like A Dude

Former child star Jessie Cornish, who at age 11 appeared on the West End in an Andrew Lloyd Weber production, is all growed-up, raunchified, and rechristened Jessie J. This record isn't my style (at all) but according to the interweb, which is never wrong, it's The Big Single of 2011. That doesn't seem impossible, as Jessie J wrote The Big Single of 2009, Miley Cyrus' Party In The USA, which went quadruple Platinum In The USA.
