Rihanna: 2009 Glamour Magazine Women of The Year Awards

Rihanna rocks the red carpet in an ultra-glamorous gown by Stephane Rolland at Glamour Magazine‘s Women of the Year Awards at NYC’s Carnegie Hall on Monday (November 9).

The 21-year-old Barbados belle, who was styled by the magnificent Mariel Haenn, was honored at the ceremony for her philanthropic work and turning her own experiences into positive ones for young girls.

Accepting her award, Rihanna shed a tear, saying she was PMSing, and thanked BFF Melissa, Mariel, Jay-Z, her label Def Jam, her granny and mom.

Earlier in the day, RiRi left MTV studios after her It’s On with Alexa Chung appearance and seemed to be in a great mood, taking photos with fans and striking fierce poses for photogs.

FYI: Rihanna‘s Glamour look was complemented by Cartier and H. Stern jewelry.
