Ludacris appeared on an episode of ‘Drink Champs’ and spoke about winning a Grammy in 2007. While talking about his win, Luda noted that he was backstage where Justin Timberlake could be heard cursing and expressing himself. Luda says only thin curtains separated artists backstage during that time. After getting a Grammy for his album ‘Release Therapy,’ the rapper noted he was celebrating his win when he heard a voice from behind the curtain saying, “Shut the f*** up, some of us didn't win any damn Grammys!”

Luda then pulled back the curtain, finding Timberlake standing there. Ludacris noted he doesn’t have any issue with Timberlake, calling the singer “gangsta.”
