The royal newlyweds are here! Prince William and wife Kate, who took off from London on a private jet Thursday morning for their two-week tour of North America, reached Canada around 2 p.m. Thursday afternoon. After disembarking from their plane at Ottawa's Macdonald-Cartier International Airport, the couple were greeted by dignitaries and cheered by thousands of fans, People reports. (The former Ms. Middleton had thoughtfully changed en route into a dress made by Montreal-born designer Erdem Moralioglu in honor of the host country – having worn a blazer designed by another Canadian, Toronto-based Smythe Les Vestes, when she boarded the plane.) After making several stops in Canada in the coming days, they will then dip into the United States to visit California.

"There's a need for a place where fans can go to interact with their favorite entertainers, listen to music, watch videos, share and discover cool stuff and just connect," Timberlake said of his vision for the site.
