Veteran fashion photographer Mario Testino has been enlisted for a special new job—but it won’t involve supermodels with legs for days. Rather, Testino’s been handpicked by Prince William and Kate Middleton to snap the official photos of their daughter, Princess Charlotte, at her christening this Sunday.

Yes, you read correctly: The new princess will pose for one of the world’s renowned photographers before she can even crawl. When your grandmother’s the Queen of England, there are bound to be a few perks.

Testino, who also took the couple’s official engagement portraits in 2011, will also capture the family portrait after the ceremony at Kensington Palace.

The high-profile choice to appoint Testino is rather unsurprising when you consider that the photographer’s also said to have been one of the late Princess Diana‘s favorites, famously capturing the Princess for Vanity Fair in 1997.

Stay tuned for more adorable royal baby snaps this weekend.
