CBS's winter edition of  BIG BROTHER comes to an end on the live season finale when the winner will be chosen, on Sunday, April 27 (8:00-9:00 PM, live ET/delayed PT) on the CBS Television Network.

The winner will have spent 81 days inside the BIG BROTHER house and will be chosen by a sequestered jury of seven that will decide who will win the grand prize of $500,000.

After 76 days in the House, only three players remain after Sharon was evicted last night. With Adam's single vote, Sharon Obermueller was evicted from the BIG BROTHER house.

Earlier in the week Head of Household Ryan Quicksall, who originally nominated Sheila and Sharon for eviction, won the Power of Veto, but chose to leave his original nominations in tact.

During last night's live broadcast, Sharon Obermueller, the 23-year-old realtor from Olathe, Kan., learned her fate and left the House.  After leaving BIG BROTHER, Sharon was interviewed by Julie Chen about her experience. Sharon becomes the sixth jury member joining Matt, Chelsia, Joshuah, James and Natalie in sequester.  One more live eviction will take place on Wednesday, April 23.

After last night's eviction, the remaining Houseguests competed in the first part of a three-part final Head of Household endurance competition called "Up A Creek" in which they had to enter the Big Brother "river" holding onto an individual rope as the river swelled and "lightening," "thunder" and "rain floods" were a factor.  In addition, as the competition progressed, the "river" elevated. The last Houseguest who survived the Big Brother "river" would win part one of the Head of Household competition and automatically move on to part three of the competition.

The losing Houseguests will have to compete against each other in part two of the HOH competition in order to advance to part three.  Viewers will have to tune in to Wednesday's live show to see the results of part one of the HOH competition as well as watch the final two parts that will determine who will be the final Head of Household.
