Madonna has revealed that her infamous lesbian kiss with Britney Spears led to her daughter Lourdes asking her if she was gay.

"(Lourdes) is really obsessed with who is gay," says Madonna in an interview in Out magazine's April issue. "And she even asked, 'Mom, you know they say that you are gay?' And I'm, 'Oh, do they? Why?' And she says, 'Because you kissed Britney Spears.'"

"And I said, 'No, it just means I kissed Britney Spears. I am the mommy pop star and she is the baby pop star. And I am kissing her to pass my energy on to her."

Madonna, 47, locked lips with Spears, 24, while performing her songs "Like a Virgin" and "Hollywood" at an MTV awards show in 2003 during a sizzling live performance.

The pop diva, considered by some to be an icon in the gay community, tells the magazine her 9-year-old daughter likes to guess who is gay: "Oh, and the other thing she likes to do when we go out, she says, 'Mom, do you want me to point out who the gay men are?' And I say, 'Okay, but I think I already know.'"

Lourdes is Madonna's daughter with actor/fitness instructor Carlos Leon. She has a 5-year-old son, Rocco, with husband of five years, filmmaker Guy Ritchie.
