Vanessa Williams
Vanessa Williams' story is one of triumph and tragedy. She won Miss America in 1983 but was later completely degraded when old nude photos surfaced. She was stripped of her title and cast into the shadows of the entertainment world. She ended up releasing a song that helped bring her back into the spotlight but was never again crowned Miss America.
Natalie Maines
Oddly enough, only Natalie Maines of the Dixie Chicks was blacklisted. The band generally did fine, but Maines was not allowed to appear on TV. She was openly against Bush's decision to invade Iraq and made it known. Apparently, that was deemed unpatriotic and she was barred from working with a lot of TV stations.
