After being nominated for eviction by Justin Giovinco, the fifth Head of Household, Nathan Marlow was unanimously evicted last night from the "Big Brother 4" house based on the votes of his fellow HouseGuests. Nathan received five votes and Jack Owens received none. Robert Roman won the Power of Veto and chose not to use it.

After the houseguests voted during last night's live broadcast, Nathan learned his fate, said his good-byes and left the house. After leaving "Big Brother 4," Nathan was interviewed by Julie Chen about his experience.

Nathan received a unanimous vote for eviction from the five HouseGuests -- Robert, Jee, Jun, Alison and Erika. As Head of Household, Justin was ineligible to vote unless there had been a tie.

The HouseGuests compete each Wednesday to become Head of Household. The perks of the position include having a luxurious private bedroom stocked with favorite foods, but it also includes the responsibility of having to nominate two fellow housemates for eviction. However, one of the nominees can be saved from the chopping block if they or another housemate wins the Power of Veto competition and chooses to save one of the nominees while giving themselves immunity from nomination. If they choose to use the veto power, the Head of Household must immediately choose another nominee.
