Acid reflux wasn't to blame for Ashlee Simpson's heavily panned performance at last week's Orange Bowl. The embattled teenybopper says a combination of technical difficulties and her pro-USC stance may have led to the chorus of boos. "There were no ear monitors when we went on stage," she told MTV.com. "And trying to sing in a stadium where you can't hear yourself is kinda hard." Or... "maybe they were booing at me, maybe they were booing at the halftime show, 'cause the whole thing sucked," she added. "I was facing [the Oklahoma Sooners], and I was rooting for USC, and they played a clip of it, so maybe it was that those people didn't like me." Actually, I think it was the scoreboard they didn't like.
