Months after Kanye West publicly disrespected the kids of his former friends Jay-Z and Beyoncé, it appears Jay-Z has fired back at his ex-collaborator. While hitting the stage alongside Beyoncé during her “Cowboy Carter” show in Paris on Sunday, Jay-Z made a very noticeable lyric change.

Jay-Z dissed his former friend Kanye West while joining Beyoncé onstage during her “Cowboy Carter” show in Paris on Sunday. The couple, who hadn’t performed together in over six years, sang “Crazy in Love” followed by “Drunk in Love” remixed with “Partition,” before Jay-Z, 55, performed his and West’s 2011 song “N—-s in Paris.”
