LL Cool J
Over his lengthy career, LL has beefed from virtually every angle: he’s been the brash youngster demanding respect from an elder and the elder statesmen admonishing an up-and-comer. He most famously feuded with the elder Kool Moe Dee in the late 80s, but also had beefs with West Coast rappers Ice T and MC Hammer. In the late 90s, he engaged in another famous feud with rhymer Canibus.
