Will Smith broke down in tears as he spoke about his nephew's response to him slapping Chris Rock at the Oscars back in March.
The 54-year-old Hollywood actor made global headlines after storming on stage at the star-studded ceremony and slapping 57-year-old Chris over a joke the comedian made about Jada Pinkett Smith.
Will issued an apology for the incident on Monday night and admitted it was 'horrific' having to explain his actions to his nine-year-old nephew.
