Hummer: Jessie J's "Nobody's Perfect"

Just a few months ago no one in America had a clue who Jessie J was. Then she walloped us with a huge hit -- "Price Tag" -- and a game-changing appearance on Saturday Night Live and now the british pop star's U.S. invasion is fully underway. Further proof of her soon-to-be Stateside domination? Another stand out single and video, this one for "Nobody's Perfect."

Keep on hustling at this pace -- and giving us more tracks like this one, JJ -- and you've got nothing to worry about.
