USC Song Girl Allison, Image from SI.com It seems SI.com has finally got the message...life is hotter at USC. The sports giant has decided to upgrade its Cheerleader of the Week format for a model that's clearly more advanced: Song Girl of the Week. And this week's honor goes to USC's Allison. This Song Girl is any decent man's dream come true. Allison not only cheers for our favorite team (and looks damn good doing it), but follows sports (San Francisco 49ers, San Diego Padres and Phoenix Suns) and loves a good philly cheese steak. Plus, under the "Three People who annoy me" question, she correctly answered: UCLA fans, the Stanford Tree and people who doubt me. Follow the jump for a link to the full SI.com Allison photo gallery.
