Christmas Abbott entered the Big Brother house convinced she can win Season 19's $500,000 grand prize.

Christmas is a 35-year-old fitness enthusiast -- or "superstar," as CBS put it -- from Lynchburg, VA, who currently resides in Raleigh, NC.

Because of her fit body and obvious muscles, Christmas was viewed as a tough physical competitor from the get-go; however, she dropped out of the first two challenges fairly quickly in order to remove the target from her back.

Christmas survived the season's first eviction after some bad luck and a temptation twist landed her on the chopping block with Cameron Heard and Jillian Parker. (Cameron ended up going home).

While she escaped the bad situation, Christmas found herself on the outside of the house's majority alliance led by this week's Head of Household, Cody Nickson, so we'll see if she can turn things around.
