MTV Movie Awards Fashion Report: Kristen Stewart's Pale Lips, Katy Perry's Neon Nails, Plus All The Little Details

OBVIOUSLY Katy Perry's now-signature blue hair and Ken Jeong's dreamy "little tiger snooze" costume were two of the biggest standout style moments from last night's 2010 MTV Movie Awards. Those, and the Jersey Shore" girls and Lindsay Lohan, who had on enough metallics to permanently deprogram all of the metal detectors at LAX. But there were also a handful of beauty trends and quirky details that shouldn't be overlooked.

Nude/Next-To-Nude Lips: Flashy dresses and obviously made-up eyes ruled the Movie Awards red carpet, but bold lips did not. Even Katy Perry followed the "play up ONE thing" rule, offsetting her blue wig with baby pink lips. Audrina Patridge and Stephanie Pratt followed suit, complementing their black-lined eyes with just a trace of neutral gloss. Meanwhile, Jessica Biel took natural glam to even hotter new places.

Pretty Ponytails! Audrina Patridge's ponytail kept her look fresh and not too overly done. Nicky Hilton's loosely braided ponytail looked picture-perfect, and Kristen Stewart's messy-on-purpose ponytail made us fall in love with her all over again.

Katy Perry's Neon Nails: You may have been too busy noticing Katy Perry's other ... assets... like her BLUE WIG, obviously. But look closely, and Katy pulled off two manis in one night! A super-summery neon yellow for the red carpet, and hot pink during her "California Gurls" performance. That's a seasoned showbiz pro for you, nailing every last detail.

Heavy Metals: Christina Aguilera's all about the S&M and freaky-deaky between-the-sheetsies behavior these days. (Don't believe me? Have you seen this?) So her Versace Atelier chain detail dress was the perfect way to say "I may clean up nicely, but I'm still ready to get 'Dirrty.' " And we also loved Audrina Patridge's chained-and-cuffed Giuseppe Zanotti spike heels.
