Shelly Moore is a HouseGuest on Big Brother 13. Her duo partner was Cassi Colvin. She was given a Golden Key after Cassi was evicted in the second week. When the duos twist was released back on the house in the later stages of the game, her later duo partner was Adam Poch. She finished in sixth place.
After betraying Jeff and Jordan in week 7, Shelly received numerous amounts of hate-mail and death threats from their fans. Allison Grodner, the executive producer, addressed the threats saying that it's wrong to threaten a HouseGuest's family based on his or her decisions within the game.
Shelly was the only newbie to vote for Rachel to win the game.
