"It was the first decision I made as a father," Aiken, 29, tells the upcoming issue of PEOPLE, on newsstands Friday. "I cannot raise a child to lie or to hide things. I wasn't raised that way, and I'm not going to raise a child to do that.

Aiken says he expects the news may overwhelm some of his fans. "Whether it be having a child out of wedlock, or whether it be simply being a homosexual, it's going to be a lot," said Aiken, who returned to Broadway last week as Sir Robin in Monty Python's Spamalot.

He adds that he hopes his fans "know that I've never intended to lie to anybody at all. ... But if they leave, I don't want them to leave hating me."

Aiken tells PEOPLE that his son Parker – who was conceived via in vitro fertilization with his best friend, music producer Jaymes Foster – will be raised in an environment that is "accepting and allowing him to be happy."

Says Aiken: "I have no idea if he'll be gay or straight. It's not something I'll have anything to do with, or that he'll have anything to do with. It's already probably up inside the code there ... No matter what the situation you're in, if you're raised in a loving environment, that's the most important thing."
