This week's Head of Household, Justin Giovinco, a headhunter from Pittsburgh, selected Nathan Marlow and Jack Owens, Jr. for eviction in the fifth round of "Big Brother 4" nominations on the episode that was broadcast Friday, August 8 on the CBS Television Network.

Nathan is a personal trainer from Edmond, Okla. and Jack is a former FBI agent from Birmingham, Ala.

Nathan and Jack will learn their fate live on the Wednesday, August 13 (9-10 PM, live ET/delayed PT) edition of "Big Brother 4," unless one is spared by the winner of the Power of Veto challenge on Tuesday, August 12 (8:00-9:00 PM, ET/PT). If the winner of the Power of Veto chooses to remove Nathan or Jack, the Head of Household, Justin, must immediately choose a new nominee.

Immediately following the voting results on August 13, the evicted HouseGuest will exit the house, proceed to the live show studio, be reunited with his family and talk with host Julie Chen.
