Famed photographer Mario Testino was tapped to snap the official engagement pictures of Kate Middleton and Prince William. The photos, which were taken last month, are set to be released just before Christmas.

There is a nice synchronicity to this choice, as Princess Diana has previously posed for Testino for Vanity Fair in 1997, and Testino has also shot Prince William's 21st birthday, Prince Harry's 20th birthday, and Prince Charles for Vogue UK in 2002, US Vogue earlier this year, and even Charles' official Christmas card for this year.
