Christine Brecht was a houseguest on Big Brother 16. After initially establishing a connection with fellow HG Nicole on Day 1, Christine became well liked within the house, and she became a member of The Bomb Squad and eventually the Detonators alliance. As the game progressed, both Hayden and Nicole became suspicious of Christine and her loyalty to their alliance. Christine eventually betrayed both Hayden and Nicole, assisting in their evictions. Christine also became involved in a controversial "flirtmance" with Cody despite being married. Eventually, on the live feeds, the camera zoomed in on her wedding ring as she and Cody engaged in the behavior.
Despite her loyalty to the Detonators, her fellow alliance members began to doubt her believing she was playing both sides of the house. On Day 77, Christine was evicted 3-0 against Victoria on a double eviction night after failing to win HOH and POV. As she left, she received a booing from the live studio audience.

•She is the only female to win the PoV twice in Big Brother 16.
