Watch Adam Sandler and his daughters cover Taylor Swift's 'Lover' in front of star-studded audience

Can we always be this close, forever and ever?

Adam Sandler's well-accustomed to performing live onstage, but he had two newcomers by his side this weekend at Rock4EB!, a charity event in Malibu: His two daughters, 13-year-old Sadie and 10-year-old Sunny, who joined their dad for a cover of Taylor Swift's "Lover."

Although the girls were a bit nervous to perform in front of the crowd, they were just about pitch-perfect as they sang in unison while Sandler played guitar. The audience cheered when they hit the chorus' high notes, and there quite a few notable spectators on the floor: Julia Roberts, Sean Penn, Courteney Cox, Rami Malek, David Spade and Kaley Cuoco were just a few of the famous faces in attendance.

Taking a cue from their dad's penchant for Jewish-themed jokes, the sisters swapped in a few key lyrics, substituting in "Chanukah lights" for "Christmas lights" and even tossing in a shoutout to matzo ball soup. They also exchanged the phrase "dirtiest jokes" for "corniest jokes."

A standing ovation was in order after the trio wrapped up. "Thank you for being so nice to them," Sandler said to the crowd, according to THR. "They were dying to be a part [of this]. Girls, you did great! Sounded awesome — confident and cool. I love you, now get out of here."

Sandler's longtime pal Spade also posted a video of the performance on his Instagram story.

The fundraiser benefited research and treatment for epidermolysis bullosa, a rare skin condition that is often fatal.
