Take a look back at the talented songstress' major milestones
In November 2010, the songstress performed a new single--"Someone Like You"--from her soon-to-be-record-breaking second album, 21, on the U.K.'s Later Live with Jools Holland. As calm, cool, and collected as she seems on stage, "I'm scared of audiences," she admitted to Rolling Stone in February. "I get s----y scared. One show in Amsterdam, I was so nervous I escaped out the fire exit. I've thrown up a couple of times. Once in Brussels, I projectile-vomited on someone."
