Serena Williams shared a deeply relatable video of her shocked reaction to Will Smith slapping Chris Rock at the Oscars

• Serena Williams saw Will Smith's attack on Chris Rock at the Oscars first hand.
• She reacted by sharing a video of herself with her mouth agape in shock.

Serena Williams reacted to Will Smith slapping Chris Rock at the Oscars on Sunday by sharing a video of herself with her mouth completely agape in shock.

Smith stormed the stage to hit Rock after the comedian made a joke about his wife's hair while presenting the award for Best Documentary.

Jada Pinkett Smith has spoken numerous times about her hair loss as a result of alopecia.

Following the attack, Smith then yelled at Rock from his seat: "Keep my wife's name out your fucking mouth."

Shortly after the incident, Williams — who was at the awards to celebrate the movie King Richard, a dramatization of her and sister Venus' childhood starring Smith — took to Instagram to react.

After sharing a story of her silent with her mouth wide open, she then said in a second video that she had a "sit down" and put her drink down as a result of the drama.

Smith went on to win the award for Best Actor for his portrayal of the Williams sisters' father Richard in King Richard.

Upon collecting the award, the 53-year-old cried as he apologized to the Academy for his actions but did not say sorry to Rock.

"I want to be an ambassador of that kind of love and care and concern," said Smith. "I want to apologize to the Academy, I want to apologize to all my fellow nominees.

"This is a beautiful moment and I'm not crying for winning an award. It's not about winning an award for me; it's about being able to shine a light on all the people and the entire cast and crew of King Richard and Venus and Serena and the entire Williams family.

"Art imitates life. I look like the crazy father, just like they said about Richard Williams! But, love will make you do crazy things."

Smith ended his speech by saying: "I'm hoping the Academy invites me back."
