LOS ANGELES, CA -- A North Carolina "fitness superstar" is ready to expect the unexpected.

33-year-old Christmas Abbott is competing on the 19th season of the CBS reality show Big Brother.

Abbott lives in Raleigh, and was the first female in NASCAR Sprint Cup pit crew member. Now she is testing her skills in a summer long power struggle for $500,000.

She will compete against 15 other house guests. Abbott says she plans to fly under the radar so people do not think she is a threat. She says the physical and mental games are the easy parts of the game.

Abbot believes lack of privacy will be the hardest part of living in the Big Brother house.

Big Brother 19 premieres Wednesday, June 28th on WFMY News 2.
