According to HipHopGame.Com

Rumor has it that God's Favorite took it to God's Son at Puffy's party yesterday. Apparently N.O.R.E. hit Nas in the head with a flower pot. Yes, a flower pot.
No word yet on what they were arguing about, possibly botany or whether "Melvin Flint" or "Nastradamus" was a worst album...but apparently Nas took a pot to the dome. HipHopGame knows one thing...that's not the type of pot Nas expected at Puffy's party!

LMAO if thats true. N.O.R.E is pretty wild though so I wouldn't be surprised...
