It may have been a royal premiere, but there was only one queen reigning supreme on the red carpet this evening for ‘The Hobbit: An Unexpected Journey’ screening at the Empire Leicester Square, and that was Cate Blanchett.

The Australian actress wore a winter-white Givenchy Spring 2013 gown.

Considering the near-freezing temperatures in the capital this evening, Cate was wise to wear this long-sleeve, side slit, high-neck gown with gold metal accents on both shoulders and inside the cuffs, but the surprise feature of this look was the open back.

The elegant gown was styled with a white Givenchy envelope clutch and Givenchy Spring 2013 fashion-forward heels.

I don’t know about you, but I think I just died and went to fashion heaven.
