Gia Mantegna models off dress number one on the red carpet at the 2011 Golden Globe Awards held at the Beverly Hilton Hotel in Beverly Hills on Sunday afternoon (January 16).

The 20-year-old actress will serve as Miss Golden Globe during the award ceremony, which means she’ll be on hand to help hand out the awards on stage.

Gia recently dished to the Wall Street Journal on some of the nominees she’s rooting for. She shared, “Claire Danes in Temple Grandin. I have a sister with autism and I think Claire did a phenomenal job. I’d love to run into Claire and tell her how great she was in that movie.”

FYI: Gia is wearing Kwiat jewelry and a Lorena Sarbu lace gown. She finished off her look with a Judith Leiber clutch.
