Rare footage of Princess Mary in an ad - before she was a royal!

Before she married Crown Prince Frederik of Denmark, and became Crown Princess Mary of Denmark - a 26-year-old Mary Donaldson was living in Sydney and working at an advertising firm.

The commercial was a pitch from the agency for V-Line trains and Mary ended up being placed in the ad as an extra.

Two years after this was filmed, Mary met her now-husband at the Slip Inn in Sydney, and the pair went on to tie the knot in Copenhagen on May 14, 2004.

The pair are now parents to Prince Christian, 9, Princess Isabella, 8, and 4-year-old twins, Prince Vincent and Princess Josephine.
