Mariah Carey

Ever since her divorce from Tommy Mottola, Mariah Carey has been trying to prove to the world how hot she is. Her clothes always seem to be a size too small and hemmed WAY too high. We thought becoming a mother would soften Mariah and bring out her maternal side, but the opposite happened. The singer has been showing off her post-pregnancy body in slinky dresses and in inappropriate music videos with Just Bieber (She could be his mom!). This year, we want Mariah to button it up and focus on her beautiful voice.

Paz de la Huerta

Paz de la Huerta quite literally stumbled onto the red carpet scene after she was cast in Boardwalk Empire. Since then, she's been showing up to events looking a hot Hollywood mess. First, we hope Paz starts wearing a little eye makeup. I like that she's trying something new, but there's a reason women don't leave the house without mascara - it doesn't look good! Second, we hope the actress is able to pull herself together so she's more Courtney Cox than Courtney Love.

Lauren Conrad's Fishtail Braid

New Years Eve brings with it crowded bars, a lot of alcohol, and flashing cameras. Don't start 2012 with matted, sweaty hair. Take a look at LaurenLauren Conrad's Fishtail Tutorial and bring in the New Year with a trendy out-of-your-face style.

Ombré Highlights

OK, so ombré's been around for awhile--but there's a reason why: The two-toned look works on anyone. Whether it's golden streaks like Rachel Bilson's, or warm caramel highlights for a blondie, the ombré look is great for enhancing hair color without the commitment of a full dye job. This is one hair trend we won't might bringing into the New Year.

Half-Buzzed Hairstyles

Half-buzzed hairstyles certainly had their moment this year. From Cher Lloyd to singer Cassie to Project Runway winner Anya Ayoung-Chee, it seemed like the shaved 'do popped up just about everywhere. Unfortunately the half-buzzed hair, looked just that: half-done. Leave it in 2011.
