Oscars best picture gaffe sends Twitter into frenzy

Oscar memes, gifs and hilarity are swamping social media today after La La Land was incorrectly given the best picture Oscar, when in fact Moonlight was the winner.

Organisers have been forced to apologise over the mix-up at the key moment in the ceremony, which saw the wrong envelope being opened on stage .

Some tweeters asked if the results of the US election could also have been a mistake, while others joked the awards ceremony had been hacked by Russia.

The Sixth Sense director, M Night Shyamalan, who made a name for himself with the dramatic twists in his films, joked that he wrote the ending to the 89th Academy Awards.

The official Miss Universe tweeted some advice to the Academy, two years after US comedian Steve Harvey mistakenly announced the wrong winner during the crowning of the 2015 Miss Universe.

The pageant tagged the Academy, saying: "Have your people call our people - we know what to do. #Oscars #MissUniverse."

And actor Emile Hirsch tweeted: "I'm starting to wonder if I got nominated for Into The Wild after all. #Oscars."

Here are some of the best reactions to the unprecedented blunder:
