Adele

Her first two albums were titled 19 and 21, named for how old she was when she wrote them. The first one chronicles the rise and fall of her first serious relationship, and the next one tells the story of the next guy she fell in love with, which also didn't end well.

She gets very nervous before shows, and usually doesn't eat before a performance for fear of a reversal. Her other big fear is flying: she says she's convinced she's going to die whenever she gets on a plane.

Adele got a big boost in America when she performed Chasing Pavements and Cold Shoulder on the October 18, 2008 episode of Saturday Night Live that featured Sarah Palin, who was running for Vice President at the time.
