Bjorn Borg was a Swedish tennis superstar in the 1970s and was ranked the world's #1 player after having won 11 Grand Slam tournaments. Then, at the age of 26, he stunned the tennis world by announcing his retirement. Sadly, that's when his life began to unravel; Borg divorced twice and had a child with a contestant in a beauty contest he was judging. He became addicted to drugs and was once hospitalized for accidentally overdosing. Bjorn eventually cleaned up and tried launching a clothing line and a dating site to little success; however, his latest venture, Bjorn Borg designer underwear, has been a hit.
