Adam Lambert spills the beans on a lot of things in his upcoming Rolling Stone cover story, from finally [article id="1613501"]coming out as a gay man[/article], to discussing his psychedelic fungus-fueled revelation about trying out for "American Idol" and his struggles to escape the sometimes dark, twisted Hollywood party scene.

But one of the most shocking admissions he makes is that not only is be good buddies with "Idol" winner Kris Allen, but when the two were first paired up as roommates in the "Idol" top 13 mansion, he kind of had a crush on the shy, married singer from Conway, Arkansas.

After making the top 13, Lambert sublet his Hollywood studio apartment and moved into the show's Bel-Air mansion. "I was like, 'Oh, sh--, they put me with the cute guy," Lambert said about the eventual "Idol" champ. "Distracting! He's the one guy I found attractive in the whole group on the show: nice, nonchalant, pretty and totally my type -- except that he has a wife. I mean, he's open-minded and liberal, but he's definitely 100 percent straight." A spokesperson for Allen could not be reached for comment at press time.

And while he's diplomatic about it, Lambert makes it clear that his relationship with third-place finisher, Milwaukee worship leader Danny Gokey, was not quite as easy. Lambert said the two discussed religion a few times and "Danny is by the book, and the book is The Word," he explained. "And I respect that. Just don't try to push it on me and we're cool."

You already knew Lambert was one of the most unconventional "Idol" finalists ever, but in the wide-ranging story, the 27-year-old San Diego native opens up about his childhood -- he's Jewish, but never got a bar mitzvah and hated Hebrew school because he got a bloody nose on the first day -- and how despite living as a gay man, he still sometimes gets excited when flirting with women. "I loved it this season when girls went crazy for me," said Lambert, who discusses making out with and experimenting with girls in high school. "As far as I'm concerned, it's all hot."

If it appeared to some that Lambert was [article id="1608851"]borrowing a page from last year's winner, David Cook[/article], by singing someone else's re-interpretation of songs on the show, he happily admits as much. "I saw what David Cook did last year and it was cool," he said. "He thought, 'I have to sing something everybody knows, but I'm going to make it work for me, and I'm not going to give a f--- about what the theme is that week -- and, most of all, I'm going to just ignore the pageantry of the whole thing."

Lambert also dishes on [article id="1610807"]his best friend on the show, fourth-place finisher 17-year-old Allison Iraheta[/article], who he says didn't go for the pageantry, either, which might have been what tripped her up. "That's why it's hard for people like Allison, who won't stand there and smile, say what they want her to say," he said.
