Playboy twins - 1

Kristina and Karissa Shannon (born October 2, 1989 in Ann Arbor, Michigan) are American glamour models, Playboy Playmates, and twin sisters. In 2008, the Shannons moved into the Playboy Mansion as two of Hugh Hefner's three new girlfriends.
Despite their "girlfriend" status, Karissa said the relationship she and Kristina shared with Hefner was more for fun and the opportunity to be on the show, The Girls Next Door, rather than romance.
The first episode they appeared in attracted 2.4 million viewers, making it the most-watched season premiere in the show's history.
