Christine McGraw

 was a houseguest on Big Brother 1.

Christine was known most in Season 1 for her strong personality and being brutally honest. She started a three-person all female alliance on Day 1 with Avery and Juliet. She was seemingly in a good position, but that all turned around when she was named as the Replacement Nominee in Week 1. She received two votes at the eviction, and was safe in Week 2 when her ally, Avery, won HoH. During Week 4, she played a strong part socially in taking out Jay, and she rallied the troops against him. She won the Double Eviction HoH and nominated Calliope and Robin, who were aligned with Jay, and Calliope was evicted. Unfortunately for her, Robin won the next HoH, and Mark won the PoV, and Christine was blindsided when Omid and Samantha flipped to Robin's side. Robin broke the tie and sent Christine home, ending her game in twelfth place.
