Katherine Ryan hit out at Will Smith for hitting Chris Rock at the Oscars on Sunday night, saying if the actor "couldn't take a joke, he should have stayed at home".
The television personality, 38, defended fellow comedian Chris as she told her followers being insulted was the point of a "celebrity monologue" during an award ceremony.
Hollywood watched in shock as Will, 53, got up on stage and slapped Chris for making a joke about his wife Jada Pinkett Smith's shaved head, before winning Best Actor 15 minutes later.
Chris' joke "Jada, can't wait for GI Jane 2" in reference to the film character's shaved head enraged the actor as Jada, 50, suffers from alopecia, with Will yelling "Keep my wife's name out of your f****** mouth" after returning to his seat.
Taking to Instagram stories, Katherine opened up the discussion with her followers.
When one fan wrote: "I don't condone what he did, violence is never the answer but just because Chris is a 'comedian', it means Will has to sit and watch his wife be insulted? Chris shouldn't have said it, Will shouldn't have hit him."
To which Katherine replied: "Yes, he has to sit and watch his wife be insulted, yes that's the point of the celeb monologue. Can't take a joke, stay home."
When a different follower told Katherine the "politicisation and policing of black hair has been rife for centuries, and is so complex and nuanced - Rock's derogatory comment was well below the belt and incredibly harmful", the comedian said she was well aware.
"Yes I know and maybe you don't know that Chris Rock made an entire documentary called Good Hair advocating for black women", she hit back.
The film was made in 2009, when Chris was prompted to explore the importance of hair in black culture after being asked by his daughter Lola, who was three at the time, "Daddy, how come I don't have good hair?".
It comes as Will could be facing the possibility of being asked to hand his Oscar back, as the backlash over his violent outburst grows.
The actor won up for Best Actor for his portrayal of Serena and Venus Williams’ father Richard in the critically-acclaimed drama King Richard, but his victory was overshadowed by his assault on Chris earlier in the evening.
On Monday evening, Oscars organisers announced they are launching a formal review following the incident.
The statement read: "The Academy condemns the actions of Mr. Smith at last night's show. We have officially started a formal review around the incident and will explore further action and consequences in accordance with our Bylaws, Standards of Conduct and California law."
The statement released by AMPAS follows a late night tweet after the altercation, in which they posted: "The Academy does not condone violence of any form."
The probe could see Will ejected from AMPAS or suffer some sort of suspension from the organisation and its events, including next year's Oscars.
Los Angeles Police Department (LAPD) confirmed Chris declined to file a police report against the actor.
A spokesperson for the force says it is "aware of an incident between two individuals during the Academy Awards programme...[which] involved one individual slapping another".
