Sofia Rudyeva, who reigned as Miss Russia 2009 when she was 18 years-old, had a huge scandal we overlooked in about March of 2009. Rudyeva competed for Miss Universe, but before she could take the stage pictures of Rudyeva hit the Internet showing her posing without clothes on.
The scandal almost prevented Rudyeva from competing for Miss Universe, but after apologizing and admitting the pictures were of her, the pageant officials allowed her to compete, and she lost.
