Jay Z grew up Brooklyn, and Kimmel noted that he went to the same high school as the late Notorious B.I.G. and Busta Rhymes. "Me and Busta Rhymes actually had a rap battle in the lunchroom," Jay Z recalled.
The 45-year-old played coy when asked who won that battle. "I love Busta Rhymes," he said with a smile.
Another highlight of the evening was when Jay Z brought Kimmel and his entire audience over to the Barclays Center for the Tidal X: 10/20 concert. Jay Z himself performed, along with Beyonce, Nicki Minaj, Rick Ross, Lil Wayne, Usher, Nick Jonas and T.I.
