Nene Tamayo (born Jennivev Santillan Tamayo on September 27, 1981 in Romblon, Philippines) was one of the 13 housemates of ABS-CBN's Pinoy Big Brother, Season 1. Finally after spending 111 days inside the house, Nene landed as the grand winner dubbed as The Big Winner garnering 554,906 votes or 48.9% of total votes in the Big Night held at Clark Expo Amphitheater, Angeles City, Pampanga on December 10, 2005.
Nene had once been thought of as a tomboy since she played boys' games and climbed coconut trees during her childhood years back in her hometown.
Life in Pinoy Big Brother
She's best known as the dancing diva and the 'astig' (tough) housemate because of her past military background as an ROTC officer in University of the East, thus Kumander Nene (Commander Nene) was her popular tagname. Nene is also known as Nenegizer (alluding to Energizer batteries) because of her strong and long-lasting stamina; this was given during the dance marathon challenge of the housemates.
