Out singer Adam Lambert is happy for Sam Smith's uncontroversial coming out.

Lambert covers UK gay glossy Attitude's May issue.

The 11-page spread includes an interview in which Lambert gushes about the Grammy winner.

“Sam Smith, hats off, he has had an amazing year, he's a lovely guy,” Lambert said. “I've met him a few times. I'm so happy for him, and I'm so happy his sexuality wasn't a big thorn in his side. It was just: 'This is who I am, I'm cool with it and so you should be too.' And his songs are timeless and beautiful, and everybody relates to them. He's doing it right, for sure.”

When asked about a fraternity among gay artists, Lambert answered they're “building a little clique.”

“I think with me and Sam, there's definitely an understanding there, like: ‘Hey gurl, how you doing?’ [laughs] But you know, there’s only a few of us actually, on a mainstream level. I think we’re building a little clique, I hope, but I haven’t met that many. I mean, Elton John is amazing, what a sweetheart, and Boy George is also incredible. I’ve sat down and had lunch with him before, he’s so smart and has been though A LOT, and now he’s in a really good, healthy space, and loves music and is DJing and is still really connected to pop culture. He was really interesting to talk to.”

Lambert will release the single Ghost Town, from the upcoming album The Original High, on April 21.
