Hollywood came out in full force at the State Dinner in honor of Canada's Prime Minister Justin Trudeau on Thursday night in Washington D.C.
Canadian actor Ryan Reynolds brought wife Blake Lively to the White House, where the couple stole the spotlight at the fancy soiree.
The actress looked picture perfect in a silver Ralph & Russo wrap gown that featured cutouts along the shoulders and a high slit. She completed her elegant ensemble with Lorraine Schwartz jewels and tousled blonde waves. Her handsome hubby was dapper as ever in a Burberry tuxedo.
Fellow Canadian stars including Michael J. Fox, Mike Myers and Sandra Oh also were in attendance, and singer Sara Bareilles performed at the event.
Meanwhile, Michelle Obama stunned in a custom, embroidered blue dress by Jason Wu, which she paired with full, loose waves, with her bangs swept to one side.
Trudeau's wife, Sophie Grégoire-Trudeau, sported a bright purple dress by Canadian designer Lucian Matis with floral, pink appliques.
While we didn't get a full glimpse of Malia and Sasha's dresses, we couldn't get over how grown up these two looked sitting down for the star-studded dinner.
Malia, 17, looked gorgeous in a strapless cream dress, while her younger sis, 14, added a pop of color in an embroidered bordeaux design. She styled the show-stopping look with a braided updo and a black choker.
These siblings have certainly turned into mini fashionistas!
