"It didn't feel like a coming out ... I came out when I was, like, four years old," Smith, who recently nabbed two American Music Awards for New Artist of the Year and Favorite Male Artist, said. "My mom said she knew when I was, like, three, so I didn't have to actually properly come out."
He went on to note, "I kind of felt like I just had to mention it before I released my record ... If I did it afterwards, people probably would've thought I was lying just to sell records, which wasn't the case."
The singer, 22, also clarified headline-making remarks he made his role within the lesbian, gay, bisexual and transgender (LGBT) community earlier this year, noting, "Of course I do [want to be a spokesperson for the gay community], but I want to be a spokesperson for everyone, you know?"
It's been quite a year for Smith, whose hit singles "Stay With Me" and "I'm Not The Only One" have been dominating airwaves all throughout 2014. Earlier this fall, he was named Breakout of the Year as part of Out Magazine's annual OUT 100 list.
