The Prime Minister's daughter has graduated from the Paris College of Art, sporting a shock of bright pink hair.
Stephie Key, known for her risque artworks under her pseudonym Cherry Lazar, excitedly posted a photo from the big day to her Instagram page, telling followers "Ya gurl just got a degree." (sic)
John Key and his wife Bronagh were also both in Paris to see their 22-year-old daughter graduate.
Key told his own Instagram followers it was an "incredibly proud moment".
Stephie Key first moved to France when she was 17 to complete her high school education near the Geneva border. She then went on to study at the Paris College of Art, where Cherry Lazar was born.
Her artworks have garnered plenty of attention over the last few years, especially those that have seen her photographed naked but for some strategically placed Big Macs and sushi.
But this isn't the last we've seen of Lazar. Key told her college's website that she wants "world domination" post-graduation.
"I want to push Cherry Lazar into a global icon of doll, makeup and perfume.
"I'm also interested in working in film, so I would like to explore some of that."
