Prince William and Kate Middleton boarded a British Airways commercial flight in Los Angeles Sunday bound for their London home, but not before taking North America and more precisely Los Angeles by storm.

Moments before leaving, Kate issued her first public words of the couple's three-day visit to America.

"Really enjoyed it, thank you," Kate said in impromptu remarks to a reporter asking how she liked her first trip to the U.S. as the couple greeted fans staked outside the British consul's residence in the city's Hancock Park neighbourhood where they stayed.

The few words immediately provoked a media frenzy as commentators rushed to analyse the words uttered by the woman who has been at the top of the headlines for the last few days.

Since ever the royal couple touched down on U.S soil, the public, even joined by Hollywood's most A-list stars have been under the couple's spell.

"I know inside she is nervous," Arthur Edwards, royal photographer for the U.K.'s Daily Sun told ABC news "But it doesn't show, and that's what's important. She looks confident."

Having out-shone Hollywood's glitziest stars at a red-carpet, black-tie dinner for the British Academy of Film and Television Arts the night before, Kate and her groom displayed their confidence, and compassion, but also established themselves as close to the people and much more approachable than many first thought.

On Sunday, the couple saw another side of Los Angeles when they visited Inner City Arts, an arts academy for disadvantaged children on skid row, one of the city's most impoverished neighbourhoods.

There William once again showed his lighter side once again, as while both he and his bride painted alongside students from the art academy, he spontaneously asked Kate while looking at her painting "What the heck is that?"

Sunday's agenda also included a private breakfast with patrons of Tusk Trust, an African wildlife conservation group, and a final stop with the group ServiceNation: Mission Serve, for jobs fair with combat veterans.

"This is the last event on our tour of North America, but to my mind, it is one of the most important," Prince William told the audience as he stood in front of a giant American flag at Sony Pictures Studio, where the jobs fair was held.

He also wrapped up his remarks by telling the audience "how grateful we are to have been welcomed so warmly in the Golden State and the City of Angels. Thank you so much."
