It’s been quite the 48 hours for British singer Sam Smith. First he performed Bond theme ‘Writings on the Wall’ at the Oscars, then he took home the best original song award. But his big moment was quickly overshadowed by his speech, in which he mistakenly said he was the first openly gay Oscar winner. Then there was 2009 Oscar winner Dustin Lance Black, who called out the singer on twitter and accused him of texting his fiancé Tom Daley.

Sam SmithSam Smith has apologised to Dustin Lance Black after his Oscars mix-up.

After Smith’s speech Black tweeted, ‘Hey @SamSmithWorld, if you have no idea who I am, it may be time to stop texting my fiancé.’ Backstage at the awards, Smith was told of his mistake and said: “Shit! Fuck that! Two’s my lucky number, so it’s all good. Who was the other person?”

Smith is of course not the first or even the second openly gay Oscar winner, but he made the error after reading an interview with Ian McKellen, where the acting legend had said: “No openly gay man has ever won the Oscar; I wonder if that is prejudice or chance.” However McKellen’s comments were in regard to the Best Actor category, not the awards as a whole.

The next morning Smith took to twitter to address his faux pas, ‘So hungover. genuinely feels like a dream,’ Smith wrote. ‘Second openly gay man to win an oscar or third or fourth or 100th, It wasn't my point. My point was to shine some light on the LGBT community who i love so dearly.’

Smith then tweeted Black telling him: ‘Apologies for the mix up @DLanceBlack I'll be sure to check out your films now x Belated Congrats on the Oscar x.’ The screenwriter accepted Smith’s apology and also brushed off his comments about Smith texting his fiancé as a joke.

‘Congratulations. Drink water. Rest. But do check out some of the other Gay Oscar work out there. Some truly wonderful stuff,’ Black told Smith. Clarifying his tweet from the previous night, Black added, ‘THE POINT: knowing our LGBTQ history is important. We stand on the shoulders of countless brave men and women who paved the way for us.’

Ian McKellen also tweeted regarding Smith’s speech, saying: ‘I'd said no openly gay actor had received #Oscars-that doesn’t detract from @samsmithworld achievement. Congratulations to him & all others!’ The singer soon replied and offered his apologies, tweeting ‘Thank you Ian xx I am a huge fan xx Sorry for the hiccup.’
