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.”

West tweeted about the couple’s 8-year-old twins, Sir and Rumi, in March. The “Stronger” rapper expressed regret — only to walk that back.
