When we think of the St. Lunatics, it's usually in a positive manner when it's in regards to Nelly.

But times have changed and Ali of St. Lunatics is the one doing the dissing and finger-pointing.

Ali jumped on Instagram two days ago and dropped a long message accusing Nelly of hustling him into writing for him and then not giving him credit.

Well, Nelly must have caught wind of the post, and he aired out his issues in a new interview. 

In the 90-minute clip, Nelly accused Ali of not showing up to all his shows, or interviews, and that "Country Grammar" was supposed to be a group record, but things didn't fall into place. 

Skip to the 30-minute mark to hear Nelly break down the issues with the group.
