As Prince William and Kate Middleton continued their tour across Canada today, touching down at Calgary International Airport, they fulfilled the wish of a sick little girl.

In the midst of strong winds, the royal couple exchanged hugs on the tarmac with a young fan, 6-year-old Diamond Marshall, who was diagnosed with Stage 4 undifferentiated sarcmoa last December, The Star reported. The little girl's biggest wish was one day to meet a real princess.

The duchess wore a gorgeous Jenny Packham summery yellow dress for their latest stop.

The royal couple were also presented with traditional white hats by the city's Naheed Nenshi. Kate and William are wrapping up their stay in the Great White North and tomorrow they'll make their way south to Los Angeles.

There's a full day planned, as well as a reception in LA tomorrow night, followed by a polo match in Santa Barbara Saturday morning and a black-tie BAFTA gala later that night.
