The Academy Awards has launched a formal review and held emergency talks overnight to discuss whether Will Smith should be stripped of his award after he attacked host Chris Rock.
The assault, which shocked viewers and audience members alike, came after the comedian made a joke about Jada Pinkett-Smith's bald head, calling her 'G.I Jane'.
The comedian and actor was referencing the 1997 film G.I Jane in which actress Demi Moore shaved her head. Pinkett Smith told Billboard in December she has been battling the autoimmune disorder alopecia, which can cause hair loss and balding.
After initially appearing to laugh along, Smith leapt from his seat, stormed on stage and slapped Rock across the face.
"Keep my wife's name out of your f**king mouth," Smith said as he returned to his seat from the stage.
A stunned Rock said, "I'm going to", before continuing. Rock was on stage to present the category for best documentary. He had already made a few quips about those in the audience before turning his attention to Pinkett-Smith.
After the altercation with Smith, Rock joked that it was "the greatest night in the history of television", but seemed shaken and hurriedly brought his award introduction to a close.
Despite the altercation, Smith went to win the Oscar for Best Actor for his role in King Richard. In his acceptance speech, he apologised to the academy and his fellow nominees - but not Rock.
Acammy organisers condemned Smith's actions and said a formal review is underway.
"The Academy condemns the actions of Mr. Smith at last night's show," a spokesperson said. "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."
While Smith may face disciplinary action, it's unlikely he will be forced to give up his prize.
Regardless the assault didn't seem to phase Smith who was seen partying into the night at the famous Vanity Fair after-party.
Social media photos show the actor dancing and singing to his own music and posing for photos with friends.
It comes after the Los Angeles Police Department (LAPD) confirmed Rock was not pressing charges over the assault.
"The individual involved has declined to file a police report," the LAPD said in a statement sent to media.
Should Rock change his mind, however, Smith could be in trouble.
"If the involved party desires a police report at a later date, LAPD will be available to complete an investigative report," the statement said.
In a statement after the ceremony, the Academy said it "does not condone violence of any form".
