The Princess of Wales met Sir Paul McCartney and Tracey Emin as she re-opened the National Portrait Gallery following its three-year, £41.3 million refurbishment.
Kate Middleton, who is patron of the gallery, officially opened its new doors in London on Tuesday ahead of its re-opening to members of the public later this week.
She met former Beatle Sir Paul and his wife Nancy Shevell in the gallery gift shop, with the three speaking about his own art collections.
