Tiffany & Co. Holiday 2011 Video Campaign

Talk about a fairytale in New York!

For Holiday 2011, Tiffany & Co. has outdone itself (no small feat) with an utterly enchanting commercial that sees model Laetitia Casta and actor Lee Pace as lovers romancing their way through a snow-covered New York City.

Titled Some Holidays are Unforgettable, the video has Nat King Cole crooning "The Very Thought of You" (swoon) as Casta and Pace give Carrie and Big a run for their money.

While Pace looks dashing in a tux and suit, respectively, Roberto Cavalli campaign star Casta stuns in a sleek grey coat and black and pale pink gowns throughout the shoot. 

And let's not overlook the bling. As expected, there are plenty of diamonds on display as the couple hit up the New York Public Library, Empire State Building, and Central Park.

We're totally smitten ... but not surprised. After all, who does a good New York City love story better than Tiffany?
