Sources told People the audience at United Center "went wild" and gave a standing ovation after Grande and Streisand performed "No More Tears (Enough is Enough)," a 1979 duet Streisand originally recorded with Donna Summer.

"The entire theater turned into a dance party immediately," a source said. "The whole place got up."

Streisand had teased a collaboration with Grande Monday by posting a photo of just their hands.

"Made a new friend," she wrote.

Grande had her own concert Sunday in Chicago and will kick off the European leg of her Sweetener world tour Aug. 17 in London.

She released the new single "Boyfriend" last week.

Streisand will next perform her Simply Streisand show Aug. 23 in Milton, Del.

She last released the album Walls in November, which includes the single "Don't Lie to Me."
