Singer Clay Aiken is set to reveal the worst kept secret in America - he's gay.

According to new Internet reports, the former American Idol star will 'come out' in the new issue of People magazine, as part of a photospread featuring him and his new baby son Parker, who was born in August (08).

In the exclusive big reveal, Aiken explains he decided to tell the truth because "I cannot raise a child to lie or hide things."

The singer has been dogged by gay rumours for the past two years after an alleged one-night stand took his story to the U.S. tabloids.

Aiken has refused to talk about his sexuality ever since.

He's not the first star to 'come out' to People magazine - pop star Lance Bass confirmed he was gay in the publication in 2006. (c) WENN
