Adam Lambert has revealed that has slept with "a few" male Hollywood stars who have not come out.

The singer is openly gay and he told the June issue of Glamour magazine that he has bedded some famous men who are straight in the public eye.

The US star said: "I’ve been with a few of them.

"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 movie-goers and record-buyers, surely it shouldn’t matter so much?"

The 33-year-old vocalist added that he had sex with a woman a few years ago, saying:

"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.

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