Jay-Z appears to have dissed Nicki Minaj by bringing up her husband, Kenneth Petty , during a freestyle at the Roots Picnic in Philadelphia.

One line seemed specific to Nicki Minaj and her husband’s status as a registered sex offender. "That lady back on that stuff, she sounds like she's in love with ‘em/Her Ken can't even… pick they kid… enough of them/A rapper can't be my opp, I got MAGA Republicans/Those shots came from the very top of the government, good luck with them,” he rapped.

During the same freestyle, Jay-Z also seemingly shaded Drake, who dissed him on Iceman , and Ye, who brought up Hov’s children on social media last year.…
