After months of speculation about his sexuality, "American Idol" runner-up Adam Lambert has finally come out, telling Rolling Stone magazine, "I don't think it should be a surprise to anyone to hear that I'm gay."
"I'm proud of my sexuality," he adds. "I embrace it. It's just another part of me."
As to why he did not come out publicly earlier, Lambert says, "I'm trying to be a singer, not a civil rights leader."
