Sink your teeth into Robert Pattinson's past and you'll find that Edward Cullen's alter ego has some pretty impressive vampire lineage himself, according to Ancestry.com.
The online family history resource announced on Wednesday that the "Twilight" star is related to Vlad III Dracula, the inspiration for Bram Stoker's legendary bloodsucker.
Pattinson and Vlad likely are related through the British royal family, members of which the hunky star can also number among his ancestors (see chart above).
Born in Transylvania, Vlad, also known as Vlad the Impaler, was a three-time ruler of a region of present-day Romania, which he ruled from 1456 to 1462.
