Watch: Mariah Carey thrills fans by belting out new single on 'Fallon'...

Just for laughs, Mariah Carey recorded an impromptu performance for the lambily after the taping of 'Late Night with Jimmy Fallon' earlier this week.
In one impromptu performance of new single 'The Art of Letting Go', the legendary warbler showed fans that her voice is still very much... in tact. That's good. If only she was just as driven to serve us a viable hit single, and quick! Without one, that new album will never see the light of day.
