Jack White is now one of the most famous guitarists of all time, but at one point, his personal life was very much part of his act. In 1997, Jack (born John Anthony Gillis) cofounded rock duo The White Stripes with his then-wife, Meg White. Earlier in their career, however, the pair claimed they were brother and sister. Even after proof of their marriage - and 2000 divorce - emerged, Jack continued to say they were related. He eventually explained that he thought a sibling relationship would keep the focus on their music rather than any romantic connection between them.
