CHICAGO— Ariana Grande made a surprise appearance at Barbra Streisand's concert Tuesday night at the United Center to sing a duet together.
Streisand's "The Music, the Memories, the Magic" tour had a packed audience. The two singers sang "No More Tears", a song Streisand originally sang with Donna Summer in 1978.
Grande apparently stuck around Chicago after she had her Lollapalooza performance on Sunday night.
Streisand posted a photo on Instagram before the concert with a picture of her hands and someone else's with the caption, "Made a new friend...". One fan commented, "I would know those hands anywhere" and other fans said Grande's unique tattoos gave them a hint there would be a surprise performance.
Both women posted each other on their social medias after the show.
