True Blood beauty Anna Paquin could have arrived at the show's Season 2 premiere in her signature on-screen T-shirt, and we'd still drool. But in this elegant ensemble, it's tough not to take a bite.

Has True Blood's new season premiered yet? No? Then button up that jacket and walk away, Stephen Moyer. Your nighttime attire is too hot to handle until we get you back on TV.

Megan Fox has been certified hot by lad mags so many times over that she's ready to push the fashion envelope with her naughty, prom-like number. But even Maxim's No. 2 sex-pot can't get away with this fiasco at the Transformers: Revenge of the Fallen premiere in Tokyo.

Somehow, Madeline Zima's Californication character managed to seduce the show's sexy writer-in-residence, Hank Moody (aka David Duchovny). Rest assured: It did not happen in this dress.

Our parents always said that taste and money is an admirable combo, and now we get it. Taking Evan Rachel Wood's ensemble at the Young Hollywood festivities as an example, we're adding stilettos, rock-star glamour and never-ending legs to our elders' fabulous words of wisdom.
