While the cause of the brawl is unclear, some are speculating that the initial argument concerned Rihanna, whom both Brown and Drake have dated. Brown is currently on probation for assault charges involving Rihanna in 2009.
Early Thursday, Brown tweeted picture of his wounded chin, which was later taken down. The photo is still available through a Twitter search.
According to New York City police, five people were injured in the fight, including the two hip hop artists. The artists reportedly threw bottles and punches at each other, though nothing has been confirmed beyond the reported injuries. As of 11 a.m. MST, no arrests have been made. –Kelsey Fowler
