Billy Joel was joined by pop star Olivia Rodrigo during his latest Madison Square Garden residency show.

Joel gave Rodrigo quite the introduction naming off her many accolades and adding, “I like her music and so do my kids.” Rodrigo returned the favor before they performed her song “Deja Vu,” which name-checks the Piano Man in the lyrics.

Following “Deja Vu,” Joel and Rodrigo then performed “Uptown Girl,” which Joel noted was requested by Rodrigo.

The entire moment can be seen in the fan-shot footage below.
