Michelle Obama has proved yet again that she has no airs and graces, jumping onstage to ham it up with Bruce Springsteen during a recent concert in Barcelona, Spain.

A clip is doing the rounds on social media showing Michelle joining Springsteen on stage to sing backing vocals and play the tambourine as he belts out the vocals to his hit song “Glory Days”.

The video, as posted on Michelle's Instagram platform,  shows a very proud former president of the  USA, Barack Obama, at the beginning fp the clip saying, “How cool is my wife!?”.
