Adam Lambert has opened up about his past conquests revealing that he bedded various male Hollywood stars.

Speaking to Glamour magazine the openly gay singer, who shot to fame on American Idol in 2009, said that he had romped with a number of closeted household stars. Although he did reveal the identities of the men, he suggested that the macho culture of the industry may be the reason they are playing straight.

"I've been with a few of them," he told the publication. "Whether it's music or acting, you've got to remember that those industries are primarily run by men, so maybe it's about that.

"But with women being the primary moviegoers and record-buyers, surely it shouldn't matter so much?"

Lambert, who occasionally performs with legendary rock group Queen as the Freddie Mercury stand-in, also admitted that he had experimented with women.

"I think women are beautiful – and I always notice when girls smell really good. Like most gay men, I'm drawn to really confident women. I have slept with a woman before," he said.

"I did it for the first time when I was 29. It was a random thing but I was very curious. It felt great," he smiled.

Lambert's racy revelations come days after he released his new single Ghost Town, taken from his forthcoming new album The Original High.
