Barely a week and the reign of Miss Universe 2011 might end very soon. Argentine newspaper Infobae alleged Miss Angola, Leila Lopes, submitted falsified documents to qualify for the Miss Universe pageant which eventually helped her win the crown.

However, this is not the first shadowy incident to have occurred in the history of the Miss Universe Pageant. The beautiful winners have often been found to get involved in various scandals and then been dethroned or forced to resign from their glory.

If dethroned, Leila Lopes will join the bandwagon of the most beautiful women in the world who once were embraced and then cast off by the Miss Universe organizers.

Check out the photos of beautiful winners involved in different controversies over the years.
