Jessie Kowalski was a houseguest on Big Brother 15. She was a target in Week 1 for being deemed "annoying" by HOH McCrae, but she survived eviction due to a larger target sitting next to her. She began a showmance with Judd Daugherty; however, the two had a falling out which later led to his eviction. In Week 7, Jessie was targeted mainly by Amanda for calling her out. Jessie was evicted that week by a unanimous vote and placed tenth because Judd returned to the game.
Jessie Kowalski is 25 years old and was born in Beaumont, Texas. She currently lives in San Antonio, Texas and is unemployed.
