Barack Obama may have cracked jokes about just who is Canada's favorite Justin, but at a glamour-filled White House last night the First Ladies were clearly the center of attention.
The first state dinner of Obama's final year, which was also the first attended by Malia and Sasha Obama, honored Canada and its dashing new liberal leader – and was the first hosted by the White House for America's northern neighbor in nearly 20 years.
And spring appeared 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.
Sophie is a former TV host in Canada and worked as an entertainment reporter for several TV networks before marrying her husband.

After they wed, Mrs Trudeau then immersed herself in charity work, mainly focusing on issues such as mental health, eating disorders, and women's issues.
The couple have three young children, a daughter and two sons.
Both she and Michelle 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
Then it was Trudeau's turn to take the stage, where he said the U.S. and Canada are more than friends and like siblings, except Canada is more 'stay-at-home' and U.S. is more 'rebellious.'
He thanked Obama for efforts on climate change, saying it's time to discard 'the outdated notion' a healthy economy and environment 'stand in opposition.'
