After the performance, Grande took to Instagram to thank the legendary singer, writing: "Shaking and crying. Thank u Barbra Streisand. Don't have words yet". She also shared a picture of the two.

This past weekend, Ariana Grande headlined Chicago's Lollapalooza and used her stay in the city to unite with Streisand. The 'Thank U Next' singer also released a new song, 'Boyfriend', last Friday.
