Tuesday night's star-studded Madison Square Garden concert was led by Billy Joel.
Following their wedding at City Hall, Greta Gerwig, 40, and Noah Baumbach, 54, enjoyed the show with Elvis Costello, 69, and two extremely special guests joined the Uptown Girl singer, 74, on stage.
Joel's eight-year-old daughter Della and six-year-old daughter Remy led their father in a lively performance of Jingle Bells.
The girls, who Joel shares with his 41-year-old second wife Alexis Roderick, sang while donning matching green outfits with a leather-like texture and black tights. Adding a red and green cap to their ensemble, Della and the sisters stood adorably close to one another for their unexpected performance.
In addition, Joel shares a 36-year-old daughter named Alexa Ray Joel with his former spouse Christie Brinkley. The performance on Tuesday was a component of his yearly schedule at Madison Square Garden.
After a decade of monthly performances at MSG, the Piano Man hitmaker announced in June that his run of shows would cease following his 150th appearance at the storied facility. On October 20, the singer of New York State of Mind kicked off his final ten performances in New York City.
Since 2014, Joel's residency has been a cornerstone of the entertainment industry in New York City, and he now holds the record for the most consecutive appearances at the most renowned arena in the world.
Joel said, "I'm kind of flabbergasted that it lasted as long as it did. My team tells me that we could continue to sell tickets, but ten years, 150 shows - all right already!' 'I do remember the first time we played Madison Square Garden, it was the pinnacle of my career. I thought, 'My God, I'm headlining Madison Square Garden."
"Everybody in the world knows when you play The Garden, it's not just New York. To our audience, I want to thank them for coming to our shows for this long. Even after 150 lifetime performances, it's difficult to end. I simply wanted to express my gratitude to everyone for everything that has gone so well here."
Baumbach and Gerwig, newlyweds, showed up to the concert dressed in their wedding attire. Greta was seen wearing a pleated skirt over a bridal white blazer and top.
Noah, meantime, looked sharp in a dark navy suit.
"They were both glowing and celebrating. They are so happy," a source told Page Six.
Before going to Joel's play, the couple apparently told folks at City Hall about their marriage.
