The Michelle and Sophie show! Mrs. Obama meets her match in the Canadian Prime Minister's wife as the two show off their best moves during impromptu dance off

Canadian Prime Minister Justin Trudeau, 44, and his wife, 40, are making their first official visit to Washington, D.C. this week. Michelle Obama, 52, and the President, 54, welcomed them to the White House this morning. 

Mrs. Obama looked classic in a dark green Tanya Taylor dress, which she draped with a black coat and accessorized with black pumps. Mrs. Grégoire-Trudeau also cut a stylish figure in a red and pink floral dress by Canadian designer Lucian Matis, which she matched to a pretty pair of pink-and-red heels. 

After the welcome ceremony, the two women attended an event where schoolchildren sang and danced - and they both joined in.
