Birthday girl Beyonce is the lucky recipient of a $NZ2.8 million diamond and ruby ring with a $NZ705,000 matching watch from her boy friend, rap star Jay-Z. The sexy singer, who recently turned 24, is due to marry Jay-Z next month. But the buck doesn’t stop there for Jay-Z, who left Beyonce to go on his private plane to London for 48 hours of partying – at an estimated cost of $NZ2.6 million. While there, the rapper will celebrate the launch of his fashion label Rocawear autumn/winter range, and pick up the International oan of The Year award at the prestigious GQ Awards at the Royal opera House in Covent Garden.
