The gorgeous singer and actress Beyonce Knowles is another of celebrities with belly button rings and as far as I could find on the Net it is the only piercing she has!
As for Beyonce’s belly button rings – I couldn’t find any info when she got pierced and where she shops for her belly rings. And it seems that Beyonce hasn’t opened any jewelry lines featuring belly jewelry. Although – if I find anything, I’ll let you know. And if you do – please, leave a message and write where you found it:-)
