Washington, Dec 19 : Pop singer Beyonce Knowles reportedly has two engagement rings - one real and the other "fake".

The stunner puts on the `fake' one when she's onstage and out in public.

When Jay-Z popped the question last year, along with an 18-carat diamond ring, he also gave her a less expensive imitation for concerts and parties.

"Even though Beyonce''s real engagement ring is insured, she doesn''t always feel comfortable wearing such a valuable stone," Contactmusic quoted a source as telling Star magazine.

The `Bootilicious' singer has also revealed the secret behind her happy married life.

"I feel sexiest walking round my house with bare feet and messy hair. Our relationship is very easy," she said.

"We respect each other. You know someone loves you by the way he treats and respects you.

"I think like a guy. If I do something wrong I don't get emotional," she added. (ANI)
