Shawn Johnson through the years

US gymnast Shawn Johnson has become something of a national treasure after bringing home one gold and three silver medals from the 2008 Beijing Olympics and earning enough public adoration to win the eighth season of Dancing with the Stars. Now 20, she is competing for her place on Team USA for the London Olympics in July.
