Frenemies: Rappers Who Beefed Then Worked Together
Paul Wall and Chamillionaire
Houston's unified movement took a hit in 2004 when Paul Wall and Chamillionaire took issue with one another after Wall allegedly was involved in an attack on Cham's younger brother. It took half a decade, but the two eventually buried the hatchet, having since collaborated, including on 2010's "Round Here."
