Not only does she have a great set of pipes, the British songstress (making her first public appearance since the birth of her first child) is also pretty dang lovable. With that loud Cockney accent and ingratiating "aw-shucks" demeanor, she always comes off as just one of the gals - someone you'd actually like to sit down and have a crumpet and some brandy with. "Thank you so much for letting me be a part of your world for a night," said the singer, whose "Skyfall" theme won out over Taylor Swift's "Hunger Games" tune "Safe & Sound." "It's amazing, we've been pissing ourselves laughing all night!" Now how many chart-topping artists still come off that endearing?
