Ali of St. Lunatics isn't happy with Nelly, and he's been making that clear.
His main gripe is that Nelly hustled him into writing for him and then left him behind.
Nelly has denied the charge, and recently took a sub at Ali on social.
"It's called a career and in it there are ups and downs ... some never have ups themselves so technically they've never had a career they was just was a part of some else's ... facts," Nelly typed.
Ali responded with an old clip of Nelly explaining how Ali reshaped his career and made him into a success by getting Nelly off gangbanger content and on to bars that everyone could relate to.
