He said: "Sam Smith, hats off, he has had an amazing year, he's a lovely guy. 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. I think with me and Sam, there's definitely an understanding there, like, 'Hey gurl, how you doing?'

"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."

The 33-year-old singer also spoke up about his meetings with pop icons Sir Elton John - who he dubbed a "sweetheart" - and Boy George.

Speaking in the May issue of Attitude magazine, he said: "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."
