After headlining the final night of Lollapalooza this weekend, Ariana Grande stuck around Chicago to get manicures with Barbra Streisand. And last night, as Consequence Of Sound reports, they showed off their manis onstage together during Streisand’s show at Chicago’s United Center.

In the middle of her set, Streisand brought Grande out to the stage to perform her 1979 Donna Summer duet “No More Tears (Enough Is Enough).” “I’m gonna go pass out,” Grande joked once they finished the song. “You’re just gonna find 10 pounds of hair.” Watch below.
