Barbra Streisand brought out Ariana Grande for a surprise appearance Tuesday during her concert in Chicago, and fans of both went nuts. The two performed "No More Tears (Enough Is Enough)" together and the duet left Grande in tears because she got to perform with her idol. Grande commented on the beaming photo, "I’m sobbing 🖤 love you so much. i cant. get over this. it’s just.... the most special and cherished experience ever. thank you."
