The royal couple attended an art exhibition and were presented with the portrait by Sutton-Smith's colleague Glenys Andrews of Perthshire Open Studios.
While Sutton-Smith was MIA, Vanity Fair reports Prince William's reaction was exactly what any budding royal portraitist would wish for. Glenys Andrews revealed Wills beamed and said: "Wow, it's brilliant! That's going up in my room."
The question is which room? Though Glenys Andrews claims the duchess was "wowed by it", will she really be hanging this in their Kensington Palace apartments? Or will it take prize position in the newly refurbished Anmer Hall mansion?
