President Barack Obama and First Lady Michelle Obama have celebrated Star Wars Day by getting down with R2-D2 and some storm troopers.

In footage released by the White House, the couple are seen dancing with the characters to the soundtrack of hit single "Uptown Funk".

May 4 is celebrated as Star Wars Day because of the saying "May the 4th be with you".

People across the globe celebrated the event on social media, sharing videos and images from the hugely popular film series.

But the late entry from the Obamas may perhaps be the most lasting image from this year's celebrations.
