Tila Tequila switches from Yahoo spawn to Mac guyPromiscuous MySpace friender Tila Tequila recently denied reports that her relationship with Courtenay Semel, the publicly drunken daughter of former Yahoo CEO Terry Semel, was on the rocks. But The Superficial says the Hollywood Z-lister's shot at girl-on-girl love has ended. Why does she no longer Yahoo?Gossip column Page Six spotted Tequila "hooking up" with Justin Long, best known for his role as a Mac in Apple commercials, at a Vegas nightclub on Halloween. Will the Mac preference stick? Who knows, but according the a New York Post spy, Long reportedly "asked her [Tequila] to straddle him while making out."
