The Twittersphere erupted last night after Warren Beatty read the wrong envelope while presenting the award for Best Picture alongside Faye Dunaway at the Oscars.

But others were quick to defend the 79-year-old's mistake, especially his son, Stephen Ira.

"Proud of my dad for his grace!" Ira tweeted Sunday night minutes after the shocking mistake. "It's live, stuff happens. Showbiz!"

Later, he added: "I think it was just a mix up! Mistakes happen, especially in a live show."
