In a recent interview with Larry King, out artist Troye Sivan said that actor Ian McKellen might have known he was gay before he came out.

The 20-year-old is best known in the United States for his portrayal of young James Howlett in the X-Men film X-Men Origins: Wolverine. He released his debut studio album, Blue Neighborhood, on December 4.

Sivan, who is also a YouTuber, came out gay in 2013 in a YouTube video.

“Best piece of advice you ever received?” King asked.

“That's a really good question,” Sivan responded.

“So, I was in Waiting for Godot, the stage play with Ian McKellen.”

“At your age?”

“I think I was 15. And, to be honest, I actually think he knew that I was gay. I hadn't come out yet. But I think he knew. … He, like, shook my hand and he was like, 'Keep going. You'll be fine,' or something like that. I don't know if he was talking about acting or he was talking about something more personal,” Sivan explained.
