Britain's Royal Family sure knows how to celebrate Halloween. First, they open the doors to their home haunted by Bloody Mary. Now, Prince Charles is revealing he's got vampire blood.

In an upcoming TV show designed to promote interest in Romania's Transylvania region, says that he and his family are related to Vlad the Impaler, the infamously bloody 15th-century Romanian warlord upon whom author Bram Stoker based the character of Dracula, USA Today reports.

Charles, heir to the British throne, drew on his genealogy to explain that he had a personal stake in the future of the region, which is populated with forests. He also owns a home in the region.

Charles' great-grandmother, Mary of Teck, was a Wurttemberg princess believed to be descended from one of Vlad's sons.
