Kate Beckinsale showed off her sexy back on the red carpet at the 2011 Vanity Fair Oscar Party in West Hollywood, California on Sunday night.

She dazzled on the red carpet wearing a black long sleeve Julien Macdonald dress which she teamed with a Chopard ring and a Tacori earrings.

Kate’s dress has a black sheer panel at the back which also works its way down her sleeves.

It’s far from being Kate’s greatest red carpet moment, but it works for the occasion.

I’m glad she’s back to being a brunette, I wasn’t a fan of the temporary blonde do.
