Julia Roberts, Fergie, Kyra Sedgwick and more at Glamour's Women of the Year

For 20 years, Glamour has honored women in the entertainment and sports field as its Women of the Year. To celebrate the 20th anniversary, the stars shined in New York City.

We love Fergie's one-shoulder va-va-va-voom red dress -- and of course, Ms. Julia Roberts always looks gorgeous. But holy hell, Kyra Sedgwick!  We knew you were beautiful, but dayum!  Rockin' a pink number like it ain't no thang.

"Mad Men's" Peggy Olson ... er, Elisabeth Moss sure is all grown up in her blue cocktail number and we thought skier Lindsay Vonn cut a lovely figure in a black evening gown. Other women at the event included soccer star Mia Hamm, WNBA player Lisa Leslie, Arianna Huffington, Sherri Shepherd, Alexa Ray Joel, Anna Chlumsky, Kelly Osbourne and Janet Jackson.
