Ariana Grande joined Barba Streisand on stage to perform a surprise duet at the United Center in Chicago on Tuesday night.
Together, the pair sang Streisand’s 1979 disco classic “No More Tears (Enough is Enough)”.
Streisand had uploaded a picture of her and Grande's manicured hands earlier this week, when she teased: "Made a new friend."
Following the performance, Grammy-winner Grande wrote an emotional tweet thanking icon Streisand, saying she was “shaking” and “crying” after the show.
Grande also shared a photo of her and Streisand together during rehearsals, with the words: “Cherishing this moment forever.”

Grande’s appearance at Streisand's show comes off the back of the recent release of her newest single, “Boyfriend", which is out now.
