Girls' Generation proves yet again that they're the biggest girl group in the world today by reaching 1 billion views on YouTube across their various official channels. This makes the K-pop princesses not only the most-viewed Korean girl group on Youtube, but the most-viewed girl group overall, even ahead of superstars like Destiny's Child, Spice Girls, 2NE1, AKB48, and Little Mix.

The ninesome's most-viewed video is their 2009 hit "Gee," which has been watched 120 million times. After "Gee" is "I Got a Boy," which picked up the Video of the Year award at last year's first Youtube Music Awards, beating out strong competition from One Direction, Miley Cyrus, Justin Bieber, and Lady Gaga.

Girls' Generation's astounding viral success isn't much of a surprise if you're familiar with the group. Not only are their songs insanely addictive, but the girls themselves are absolutely gorgeous. Who wouldn't want to watch them a billion times?
