Jay-Z refuses to wear his wedding ring in public. The rapper - who wed Beyonce Knowles last month - doesn't feel the need to wear jewelry as he is content with the 'ring' tattooed on his wedding finger.

A source is quoted by Fox News as saying: "He doesn't need more bling, this is a very personal thing for him and he won't wear anything other than a tattoo in public."
