MARY'S 50th BIRTHDAY RUINED!

With a cancelled party and potential family crisis, the Danish royal is under pressure

“Frederik and his mother, together with Mary’s kids, had been working for months to plan an amazing gala dinner for her 50th,” a source tells Woman’s Day. “ ey planned an epic degustation menu, music, dancing, and Fred had already put the finishing touches on a beautiful speech.”

Hundreds of guests, including European royalty, Mary’s Aussie siblings and her Scotland-based dad were due to y into Copenhagen for the glamorous event within the historic Rosenborg Castle.
