They did not attend the April 29 nuptials, but the US president and the first lady have been able to congratulate the new Duke and Duchess of Cambridge in person.
The newlyweds welcomed the VIP guests on their state visit to Britain in the lavish 1844 room of Buckingham Palace.
Kate's beige structured, V-neck underlay dress complimented her deep tan, presumably thanks to the strong Seychelles sun.
William was also sporting more colour than usual, fresh from the couple's ten-day getaway in the Indian Ocean.
Kate was smiling warmly as she chatted to Michelle, perhaps on the subject of their recent wedding which Barack told Prince Charles had fascinated the US.
Meanwhile, Prince William seemed to be deep in conversation with the president, discussing what appeared to be a more serious subject.
