I be wanting to kill that fool, but he my little brother - 50 cent comes for Floyd.

50 cent, 43, just reopened the online beef with Floyd Mayweather, 41, that was apparently closed by calling the boxing Champion his little brother on Instagram.  He wrote;

The TMZ people put camera in my face, I didn't say nothing about Champ. It just didn't feel right, I be wanting to kill that fool but he my little brother. Don't tell him I said this, I know he can't read this shit.
