Crown Princess Mary, Crown Prince Frederick and their four children - Christian, 5, Isabella, 4, and twins Vincent and Josephine, 6 months.

Posing for a portrait in the gardens of their summer estate, the family look much like any other. Four-year old Isabella tickles her baby sister while dressed-down grandparents take turns juggling the bouncing 6-month-old twins. Five-year old Christian looks absolutely smitten with his baby brother.

As far as a Royal portrait goes, it's more Aussie BBQ than Kensington Palace. Even for a republican such as myself, there is something delightful in the ease i which Queen Margrethe II and Prince Henrik relate to their Australian daughter-in-law, Crown Princess Mary, and in how hands-on they appear to be with son Frederick's grandchildren - Christian, Isabella, and twins Vincent and Josephine.

It's perhaps this impression of a close, laid-back family which gives Queen Margrethe II a satisfaction rating of 95% amongst her people, compared to Queen Elizabeth II's 75%. (Did you know Margrethe is also a chain-smoking costume designer?)

Crown Princess Mary is expected to bring her adorable brood to Australia later in the year to visit family and attend charity functions.
