The silver lining: There actually have been a number of openly gay artists who have won Oscars.

Something that Sam Smith quickly learned after falsely declaring himself the first openly gay man to win while onstage accepting his Academy Award for the Spectre theme song. One of the first people to point out that fact was previous winner Dustin Lance Black.

"Hey @SamSmithWorld, if you have no idea who I am, it may be time to stop texting my fiancé. Here's a start," the screenwriter tweeted, linking to a video of his acceptance speech in 2009 for his win for Milk.

Now, the 23-year-old singer has responded, tweeting, “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.”

Still, Smith tweeted a personal apology to Black. "Apologies for the mix up," he wrote. Then he added, possibly shadily, "I'll be sure to check out your films now x Belated Congrats on the Oscar x"

In the end, Smith didn't let the controversy dampen his big moment. "I can't put into words how I feel other than... Hungover and Insanely happy x," he posted alongside a picture of him with his statuette and a beer bottle.

Meanwhile, the "Writing's on the Wall" singer seems far less pleased with his performance during the show. When asked by BBC how it went after the fact, Smith said, "It was the worst moment of my life."

"Singing was horrible. I hated every minute," he critiqued himself.
