There were some HOT looks on the red carpet at the Cosmopolitan's New Year's Eve bash last night in Vegas and these (above) are just a few. Approximately 1500 people celebrated with Jay-Z and Coldplay, ringing in the new year in an insanely lavish venue with insanely beautiful people.

Who do YOU think took the prize for sexiest little black dress last night?: Brandy, Emmanuelle Chirqui, Gail Simmons, Giada DeLaurentiis, Haylie Duff, or Olivia Munn?

January Jones, Claire Danes and Emmanuelle Chriqui definitely had a blast at all the Emmy after parties last night - and only Claire went home with an award!

But the Mad Men nominee and Entourage star, who also looked ravishing beforehand, both looked a little worse for wear after hitting up a few shindigs in Beverly Hills. Good to know all three ladies enjoyed themselves at least!

AskMen.com has posted their list of the Top 99 Women of 2010, and while we weren't surprised to see gals like Megan Fox, Angelina Jolie, Bar Refaeli and Jessica Biel on the list, we were stunned to see some of the ladies in the top ten spots. So who made the cut?

8. Cheryl Cole
7. Penelope Cruz
6. Beyonce
5. Jessica Alba

Guess that puts Eric's plans to win her back on hold!

Entourage star Emmanuelle Chriqui was spotted getting cozy with A.J. Buckley in Hollywood. Interesting to not that A.J. once played the role of Anna Faris' extremely jealous boyfriend on Mark Wahlberg's show. Let's hope that was just acting!
