The six-year-old royal, who was also joined by mum Crown Princess Mette-Marit and dad Crown Prince Haakon, was by their side for the official reopening of Oslo's cathedral.
Dressed in a warm beige coat and cream leggings, she held her grandpa by the hand as they waited outside the 17th-century cathedral, which has been closed for renovation since 2006.
At one point the little heir, who is second in line to the Norwegian throne, also received some words from grandmother Queen Sonja.
It seems the youngster is gradually getting used to the limelight, but she still seemed timid when it came to posing for the cameras.
The little one hid shyly behind her dad's hand as the adults chatted to assembled clergy members, who included the Bishop of Oslo, Ole Christian Kvarme.
The reopening of the revamped building is set to be marked by a month-long series of services, concerts, guided tours and cultural events.
