Does Lady Gaga make you totally geek out? From her stream of smash hits and shocking performances to her unpredictable fashion choices and chameleon-like changes in hair and makeup, Gaga's got something for everyone. When the pop star burst onto the scene in 2008, no one could have predicted her meteoric rise to fame (except her, of course). Naturally, Gaga couldn't have done it without her "little monsters," the ever-growing legion of fans that idolize, emulate and, most importantly, purchase all things Gaga. Just this month, over 20,000 fans showed up for Gaga's Today Show performance in New York. We've done some digging through her 5 million Twitter followers and over 10 million Facebook friends to find Gaga's biggest fans -- the ones that just can't sleep at night without seeing her latest Twitpic or airport paparazzi shot, the folks who really geek out over Gaga. So how do you measure up? Meet them after the jump.
