Dec. 22 (UPI) -- Sam Smith and Brandon Flynn have made their romance Instagram official.
The 25-year-old English singer and 24-year-old American actor shared a first photo together Thursday following months of dating reports.
Smith posted a picture on Instagram Stories of himself and Flynn wearing matching unicorn hats in an elevator. Flynn shared the same snapshot on his Instagram account.
"Rare sighting in London," the actor captioned the photo, adding two unicorn emojis.
Smith and Flynn were first linked in October after they were spotted holding hands and kissing during an outing in New York. Smith confirmed he's in a relationship in an interview the same month.
"It's weird bringing out an album and not being single," he added of his album The Thrill of It All. "Because when I brought In the Lonely Hour, I was so lonely. But now I'm singing songs about another guy, but I'm quite happy so it's quite weird."
Smith released The Thrill of It All in November, and will kick off an accompanying tour in March. Flynn is known for playing Justin Foley on 13 Reasons Why, which will return for a second season on Netflix in 2018.
