One of Ariana Grande’s dreams came true this week.


The 26-year-old performed with one of her life-long idols, Barbra Streisand, in a surprise performance at Streisand’s concert at the United Center in Chicago, People reports.


The 77-year-old icon asked Grande to join her on stage, and the two sang “No More Tears (Enough is Enough),” a 1979 duet originally recorded by Streisand and Donna Summer. Grande has reportedly been singing the song since she was a little girl.


Earlier in the week, Streisand teased that the pair might be working together when she posted a photo of her and Grande’s hands on Instagram with a cryptic caption that read, “Made a new friend…”

A People insider at the concert said that the crowd erupted with applause and cheers when Grande came out. “The entire theater turned into a dance party immediately…The whole place got up. It was a mosh pit,” they shared.


After the performance, Grande couldn’t contain her excitement on Twitter, posting, “hello shaking and crying. thank u @BarbraStreisand. don’t have words yet goodbye.”


The Sweetener singer later posted a picture of the two on Instagram, saying, “Cherishing this moment forever @BarbraStreisand.”

This might not be the only collaboration between the two powerhouse singers. Another People insider stated that the two got along “like a house on fire.”


Could Grande and Streisand maybe even write their own duet in the future? The sky is the limit!
