President Obama selfie: President takes selfie with prime ministers at Mandela service

(CNN) - In the year of the selfie, even three world leaders can get away with the relatively new phenomenon–and at a memorial service, no less.

At an event Tuesday marking the passing of Nelson Mandela, Denmark's Prime Minister Helle Thorning-Schmidt snapped a selfie with U.S. President Barack Obama and British Prime Minister David Cameron.

A photographer at the event caught the moment. First Lady Michelle Obama could be seen sitting nearby, clearly not taking part in the photo op.
