Actor Will Smith offered apologies to Chris Rock for smacking him during an Oscar awards. Smith — who was named best actor on the night — marched onto stage during the glitzy Hollywood ceremony and hit Rock over a joke about wife Jada Pinkett Smith’s hair.

“I would like to publicly apologize to you, Chris. I was out of line and I was wrong. I am embarrassed and my actions were not indicative of the man I want to be,” the “King Richard” star wrote on Instagram.

“Violence in all of its forms is poisonous and destructive. My behavior at last night’s Academy Awards was unacceptable and inexcusable,” Smith said. Pinkett Smith suffers from alopecia, a condition that causes hair loss, and had a closely cropped head at Sunday’s ceremony.

Smith’s mea culpa came hours after the Academy condemned his behavior and said it was looking at possible sanctions.

“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,” a statement said.

Celebrities from Tinseltown and beyond reacted with shock and stunned amazement to Smith’s outburst, with some defending him and others condemning a display of “toxic masculinity.”

Booker prize-winning author Bernadine Evaristo suggested that Smith had not just wrecked what should have been his greatest triumph, but had also sullied his legacy.

Will Smith was said to have been the only fifth black man in nearly 100 years to win an Oscar for the male lead, and the first in 16 years.
