Michelle Obama brought her musical skills to a surprise onstage appearance at a Bruce Springsteen concert on Friday.

The former first lady joined the iconic musician, who is currently on an international tour with the E Street Band, for his performance in Barcelona, Spain, this weekend. According to The Independent, Obama, and actress Kate Capshaw teamed up with Springsteen's wife and bandmate Patti Scialfa to sing backup vocals for his 1984 song "Glory Days."

Footage from the concert shows Barack Obama and Capshaw's husband, filmmaker Steven Spielberg, were in attendance, dancing and filming near the stage.

Spielberg, Capshaw, and the Obamas also explored the city before the concert. The couples were photographed holding hands as they walked around Barcelona and visited the Moco Museum, home to several contemporary art exhibitions.

The former president joined Spielberg and Springsteen for a last-minute reservation at the Palace Hotel's Amar restaurant on Thursday — much to the delight of the staff, as Insider's Isobel van Hagen previously reported.

The restaurant's chef Rafa Zafra told Spanish radio station Cadena SER that the reservation was only made a few hours in advance, according to The Guardian. He also said Spanish-American chef José Andrés called him and told him it was "a very important table, but that we should please not say anything."

"And of course, I began to investigate and saw that Obama was coming, that Bruce had a concert," he said.

Zafra noted that the group appeared tired but wanted to try everything on the eatery's seafood menu.

"The one who behaved best was the one who had to work today," Zafra said in reference to the group.

Staff member Pol Perello posted a photo on Instagram Friday of the staff and chefs posing with their famous friends, writing in the caption, "The pleasure this job brings you!"
