Sunday (April 3) was the last day of 3 shows Alicia Keys had in Chicago for her Diary tour. When John Legend performed his song ‘Number One’, he usually skips over the rap and goes straight to his next verse, but on Sunday, to all of our suprise, Kanye West came out and did his rap in the song. After they finished doing that song they did a little bit of the song ‘Selfish’ together. It was great, and everybody was going crazy because we were so suprised! John Legend is amazing in concert!
