Somewhere, you just know Hilary Duff is seething. At the Teen Choice Awards held yesterday, bodacious Mean Girls nice gal Lindsay Lohan won four statuettes, among them the coveted prize for Best Movie Hissy Fit. Other "victors" included Simon Cowell (Best Reality/Variety Jackass), American Wedding guest Seann William Scott (Best Movie Sleazebag) and The O.C.'s Mischa Barton (Female TV Breakout Star from which, given her wooden acting, we can only deduce that kids thought they were voting for the actress most likely to get zits). Fox will broadcast the Paris and Nicole-hosted ceremony on Wednesday.
