NEW YORK — Bruce Springsteen propped himself on top of Billy Joel's piano to sing a duet with The Piano Man, who was celebrating a milestone Wednesday night.

Springsteen surprised the audience — who loudly cheered "BRUUUUUUUCE" — at Madison Square Garden when he walked onto the stage.

Springsteen rocked his guitar and sang, while Joel worked hard on piano. The duo teamed up for two Springsteen classics: "Born To Run" and "Tenth Avenue Freeze-Out."

Joel's Wednesday show at MSG marked his 100th at the famed venue. He started performing a monthly residency at the arena in 2014. No artist has performed at the venue more than Joel.

Joel and Springsteen hugged after their two-song performance, and The Boss kissed Joel on his head as he walked offstage.

In honor of Joel's milestone, New York Gov. Andrew Cuomo declared Wednesday as Billy Joel Day in the state.

“Billy Joel is not only one of the greatest entertainers of our time, but also a leading advocate for protecting the environment, honoring first responders and improving the lives of New Yorkers,” Cuomo said. “I am proud to congratulate Billy on this remarkable milestone, and I look forward to seeing him perform for many years to come.”
