Add Bruce Springsteen chorister for michelle obamaThe list of milestones that…because she just hit the stage with The Boss overseas at one of her shows.

Check out the video, taken on Friday night during Bruce’s concert in Barcelona. You see Michelle and the actress Kate Capshaw join Bruce’s bandmate, Patti Scialfabehind the mic to sing in the background on Springsteen’s hit “Glory Days.”

Michelle is all smiles as she sings the melody, even playing a tambourine.

No sign of her husband, former president barack obamabut you have to imagine him and Kate’s husband, Steven Spielbergwere watching behind the scenes.

As we reported…Bruce, Barack, Michelle, Steven and Kate all had dinner together in Barcelona on Thursday night — a day before the big show.

Patti also appears to have been at the dinner party, so it’s possible they planned for a special guest to appear over some great food.
