A fued with my son is about to turn violent! Please help me!?

I am the president of the Superking Rap Label. I named it after myself when me and my 14y/o son changed our names legally to help our rap careers. I am now Superking and he is Cash-Money God, and the star of my rap label. Anyway, we got into a fued over whether or not we should use the rap I wrote about the yale-harvard rowing team rivalry I went through. We got in a big fight and I said he was wack. Now he wrote a rap called "Superqueen" about me! I retaliated with a rap called "Crap-Phoney Dork". Now things are out of control, and I know we will never take over the hood if we don't work together. How can I reconcile with him?
