At 20:00 crown prince Frederik and crown princess Mary joined queen Margrethe and prince Henrik for a concert at Fredensborg Slotskirke and a dinner at Fredensborg palace, in honor of the new governors of the 5 Danish regions.
Mary wore the stomacher of her 19th century ruby set as a brooch.
Mid-October 2007 Danish journalist Trine Villeman published a book on the Danish royal family called "1015 København K – et kærligt/kritisk portræt af kongehuset" (referring to the postal code of Amalienborg).
It quickly became a bestseller, relating known and unknown details of the private lives of the Danish royals, often in a dramatic and sensationalist tone: from Margrethe's lacking qualities as a young mother, Frederik's difficult teenage years to Joachim and Alexandra's unhappy marriage.
Some new facts about Mary's early days in Denmark were revealed:
* Mary had a hard time accepting that Frederik was still in touch with his Danish ex-girlfriends and their families. Her insecurity about this culminated in tears when they were at the Ritz in Paris somewhere in 2003, for the 40th birthday of Ulrik Garde Due. When Frederik leaned over to talk to his ex, Bettina Ødum with whom he was dancing, Mary thought he was kissing her and burst into tears on the dance floor. Bettina was at the party with her fiancé Kim Bernov and went over to Mary, but she refused to talk to her. The next day Frederik attended the birthday luncheon on his own.
* Moving to the other side of the world and having to fit into Frederik's 'dysfunctional family' was hard for Mary.
* After the birth of their two children, Mary 'locked herself up' at home to care for her children while Frederik still enjoyed nights out with friends. This caused some strain on the couple.
Villeman also deplored the fact the Mary had become a stiff, nearly overly professional princess, and missed the spontaneous Mary Donaldson the Danes had seen at the start of her time in Denmark.
Villeman's book was translated into English in 2008 for the Australian market.
