Heavily Vetted: Though rumours are flying about the vice presidential pick that candidate John McCain is set to announce tomorrow morning, it seems that The Hills ingenue Heidi Montag has already let the cat out of the bag. “I am McCain’s vice president!” the avowed Republican exclaimed to OK!, adding, “Go team!” Montag is a dark horse candidate to be sure, though in boyfriend Spencer Pratt, she comes with her very own Karl Rove figure. While Lauren, Lo, and Audrina have the most to lose from this possible vice presidency, they’re not the only ones likely to greet this news by barricading themselves behind the banquettes at Boulevard 3. In a McCain/Montag administration, you see, we will all be prisoners of war. [OK!]
