2011 SAG Awards WORST Dressed Celebs

• Christina Hendricks
• Helena Bonham Carter
• January Jones

Pregnancy definitely looks good on actress Natalie Portman – she is glowing and seems to rock whatever she is wearing. Her “Black Swan” co-star Mila Kunis opted for a more modern and less classic look on the red carpet with a chiffon red gown by Alexander McQueen, which gave the illusion she was flowing like a beautiful red swan.

As for Sofia Vergara, the “Modern Family” star cannot do wrong. The blue Roberto Cavalli dress was a perfect fit that accentuated her best assets. Just gorgeous! On the other hand, “Mad Men” co-stars, January Jones and Christina Hendricks, are both on the worst dressed list simply because one was wearing too much “gold” and the other was dressed in a robe.
