The hip-hop boss was gunned down at the 1Oak nightclub in the early hours of Sunday morning (24Aug14) during Brown's star-studded bash ahead of the MTV Video Music Awards that night.
Knight was reportedly shot six times, in the stomach, chest and arm, and was taken to the city's Cedars-Sinai hospital by ambulance. He later underwent surgery and is now recovering in an intensive care unit, according to Tmz.com.
Two other party-goers were reportedly injured, and one was said to be in a critical condition.
Stars including Justin Bieber, Tyson Beckford and Black Eyed Peas musician apl.de.ap were also at the party.
Brown appeared to address the drama in a post on his Twitter.com page on Sunday (24Aug14), writing, "It's disappointing that we as a society can't have fun or enjoy ourselves without any altercations sometimes. Miss me with the bulls**t!!!"
