Madonna: 'Sex With Guy Is Incredible'

Madonna is still burning up with desire for her husband after seven years of marriage, she tells May's U.K. issue of Elle magazine.

In her new song, "Incredible," the 49-year-old sings, "Sex with you is incredible." Is she referring to her director hubby Guy Ritchie?

"Absolutely," she tells the magazine. "Sex with Guy is incredible ... And surprise, surprise, it's his favorite song on the album. Actually, maybe it's not his favorite song, but it's definitely his favorite line."

Madonna adds that Ritchie also inspired her new song "Miles Away."

"So many people have to deal with long-distance relationships," she says. "It's not easy. You have to work hard to make it work."

As her 50th birthday approaches in August, Madonna says she doesn't plan to be defined by her age.

"I'm not going to slow down, get off this ride, stay home and get fat. No way!"

She won't talk about any surgery she may have had, saying "I'm not against plastic surgery, I'm just against discussing it."

Madonna's 11th studio album, "Hard Candy," is out this month.
