The ‘Coloring Book’ rapper was performing at the Black Ball charity event, which was held by the charity Keep A Child Alive. The show, which took place at the Hammerstein Ballroom, was live-streamed on Tidal and also featured performances from the likes of A$AP Rocky and Patti Smith.

Chance’s set saw Keys join him on stage to perform vocals and play piano during a medley of the song ‘Blessings’, which appears in two versions on ‘Coloring Book’.

The rapper took to Twitter after the show to praise Keys, saying that she surprised him by joining him on stage to perform ‘Blessings’. He also linked fan-shot footage of the performance on Instagram, which you can view below.

Keys repaid the compliment by calling Chance “dope”, causing the rapper to tweet the following.

Chance was this week invited to President Obama’s final White House State Dinner. The Chicagoan attended the dinner with his father, who used to work for the President when he served as the Illinois Senator prior to taking office as Commander in Chief.

Frank Ocean was also present at the State Dinner, opting to bring his mother as his guest. While posing for photographs, Ocean gave a very short but very rare interview to reporters.
