Actor Will Smith offered apologies Monday to Chris Rock for smacking the comedian during the Oscars ceremony, as the body that oversees the awards said it was launching a formal review of the incident. 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.
