Elissa Slater was a houseguest on Big Brother 15. She quickly gained notoriety from the other houseguests for being Rachel Reilly's sister. Other HouseGuests became suspicious of Elissa's influence on the viewers as she was voted the MVP for the first three weeks. Elissa managed to survive eviction for the first two weeks, causing major chaos throughout the house. She began to play a quieter game until her ally Helen was evicted in Week 8. During the Double Eviction in Week 10, Elissa was unable to save herself with the POV and she was evicted unanimously, placing sixth.
At the finale of the season, Elissa was awarded $25,000 as the winner of the Fan Favorite Award.
Elissa Slater is a 27-year-old nutritionist born in Concord, North Carolina. She currently lives in Kannapolis, North Carolina with her husband and 8-year-old son, Reilly. She is also the sister of BB12 houseguest and BB13 winner Rachel Reilly.
Elissa is the first houseguest to be nominated for eviction by the viewers.
However, this is thought to be a mistake on voting on the viewers' part, due to Elissa being the MVP for the first three weeks, thus, America believed they were voting for Elissa to become MVP again, resulting in her nomination.
Elissa is the only houseguest to have a family member who participated in a previous Big Brother season (BB12 & BB13).
