Beyonce Knowles feels sexiest for rap husband JAY-Z when lazing around her house with bare feet and messy hair.

Knowles, 27, is rarely seen in public without a glamorous outfit, and admits she is addicted to high heels.

But she is adamant life at home with her 38-year-old rap mogul spouse is a more relaxed affair.

She told the News of the World, "I feel sexiest walking round my house with bare feet and messy hair. Our relationship is very easy. We respect each other. You know someone loves you by the way he treats you.

"I think like a guy. If I do something wrong I don't get emotional."
