R+B superstar Beyonce Knowles insists wearing bling accessories has lost its appeal - because jewellers are relentless in pursuing her to model their latest sparkling creations.

The former Destiny's Child beauty has also developed a habit of losing the jewellery she takes on loan - and doesn't want to take responsibility for the financial repercussions.

The 24-year-old says, "I think the thrill has gone. I wear so many and I am careless and I don't want to be responsible if I lose it. I've lost way too much stuff."
