Chris Rock isn't the first person to be on the receiving end of a smack from Will Smith.
There was controversy during Sunday night's Oscars when Will stormed on stage after his wife Jada Pinkett Smith was mocked by the comedian.
Jade, who has alopecia, looked visibly upset when Chris joked he was excited to see her in GI Jane 2, a film in which Demi Moore shaved her head for the role.
