Not a Belieber then, Obama? President introduces Trudeau as the most popular Justin from Canada.

Not a Belieber then, Obama? President introduces Trudeau as the most popular Justin from Canada at star-studded state dinner held in his honor as their first ladies steal the show in stunning gowns. The meeting between Canada's Prime Minister Justin Trudeau and President Barack Obama may have been the headline of the day… but at this evening's star-studded state dinner, it's the First Ladies who are the center of attention. The first state dinner of Obama's final year honors Canada and its dashing new liberal leader – and is the first hosted by the White House for America's northern neighbor in nearly 20 years. And spring appears to be the theme of the night, with both Michelle Obama and Trudeau's wife, Sophie Grégoire Trudeau, opting for floral-themed dresses. Michelle Obama looked sensational in a deep blue jacquard gown by Jason Wu, who also designed the first lady's inaugural gowns. It featured a playful flower pattern and asymmetrical draping. Michelle wore her hair in full, loose waves, with long bangs swept to one side. Sophie chose a bright purple dress by Canadian designer Lucian Matis adorned with coral flower-shaped appliques. Like Michelle, Sophie is considered a fashion icon in Canada – and her outfits at special events are widely anticipated and celebrated. Both women also sported springtime looks earlier on Thursday for a welcome ceremony at the White House. Michelle chose a sleeveless green and black frock by Toronto-born Tanya Taylor. Sophie wore a knee-length red and pink dress by Matis The dessert course is cake made with toasted Texas pecans and New England maple syrup, along with a separate hand-crafted sugar sculpture inspired by the Rocky Mountains and bearing an assortment of petite pastries with American and Canadian influences. Sara Bareilles, a favorite of First Lady Michelle Obama, is headlining the after-dinner entertainment. Trudeau, who was accompanied to the U.S. on a three-day visit by his wife and their three young children - Xavier, eight, Ella-Grace, seven and Hadrien, two - took office in November and carries one of the most famous names in Canadian political history. His late father, Pierre Trudeau, was prime minister for the better part of 16 years, between 1968 and 1984, and remains the rare Canadian politician who is recognized in America. Obama, 54, and Trudeau traded light-hearted barbs earlier on Thursday over a source of national pride for Canadians: hockey. 'Where's the Stanley Cup right now?' Obama joked, before providing the answer. His hometown Chicago Blackhawks won the National Hockey League's championship trophy last season. Trudeau tried to match Obama's trash talk, noting that three of the Blackhawks' best players are from Canada. The Stanley Cup was at the State Department on Thursday afternoon at a lunch there for Trudeau. If Obama had his way, it could be part of the state dinner décor this evening.
