Roman Holiday? No, it was Gråsten holiday

At the end of the Gråsten stay Frederik and Mary had some fun on the old Lambretta scooter which had belonged to Frederik IX. Billed-Bladet reports that after Frederik did a test drive to make sure the scooter was still in good order, Mary had a quick practice and quickly mastered the art of scooter riding before they whooshed out into the palace park with Ziggy. Mary gave Ziggy a whistle as she rode out of the gate with Frederik as passenger. Ziggy took off after them, happy to run along and Mary and Frederik were also happy, laughing with the fun of it all. The scooter had belonged to King Frederik which he used to go swimming nearby because a car was not practical. Queen Ingrid had the scooter fixed for Frederik when he turned 18. It is a vintage scooter, a 1954 Lambretta, and when Frederik and Mary went outside the palace they used some vintage helmets loaned to them by a local vintage enthusiast.




Hello! magazine has the story too:

Romantic royals Frederik and Mary scoot into action

11 August 2006

Crown Prince Frederik obviously isn't the kind of man who's afraid to let his wife Mary take the driving seat for a while. The future king was happy to sit back and let his Australian-born princess take control when the pair went for a spin on an old scooter in the grounds of Grasten Palace.
In a scene reminiscent of Gregory Peck and Audrey Hepburn's classic movie Roman Holiday, the couple took a ride on an old Vespa scooter. The romantic royals may be more accustomed to travelling in limousines or horse-drawn carriages, but they both seemed to be enjoying the chance to indulge in a little two-wheeled fun.
Frederik and Mary aren't the only big names to have discovered the delights of travelling by scooter. British celebrity chef Jamie Oliver is well-known for his Vespa, which helped him beat the traffic in London in the early days of his career.
The photographs were taken as the first in line and his wife continued their summer break at Queen Margrethe's traditional summer residence.
