All hell broke loose earlier last week between Nelly and his former manager Slim…when the two fired shots at each other over Twitter. And when we say it got nasty…..it got NASTY!!

It all started with Nelly posted the following message on his account:

One of Slim’s buddies caught wind of the diss and responded to Nelly, which didn’t make the situation any better.

Nelly quickly responded back:

Well this of course, eventually got back to Slim who decided to bring all the war guns out and take things to a level we don’t think he or Nelly could have seen coming.

Here are the rest of his tweets going in below:
