But the thing is, I hate even saying that because he's so much more than just an incredibly sexy man. He's so talented, so gifted, so thoughtful, so smart and so funny."Vetro has worked with Bailey for his character in both Wicked and Wicked: For Good. In his chat with the outlet, the coach commended the actor's work ethic."He's so humble, so he doesn't enter the lesson like, 'I'm a really good singer. I've got a great voice.' He doesn't do any of that."Vetro continued:"He's always very, very open about wanting to learn good technique. He wants to know it so well that then the character can come through and he doesn't have to think about the technique when he's actually performing. He always encouraged me, 'Give me something harder, give me something more difficult.'"How did Eric Vetro react when Jonathan Bailey was announced as the 2025 Sexiest Man Alive?When asked how he reacted when Jonathan Bailey was announced as this year's Sexiest Man Alive, Eric Vetro shared that it didn't even come as a shocker."It was this combination of complete excitement and surprise.
