WHEN you're King and Queen of the 'hip hop', all the luxuries in the world are on tap for any whim. So its no surprise that Beyoncé, 31, and her husband Jay-Z, 43, went to town to mark their little Princess's first year in the world. America's golden couple are reported to have splashed out $80,000- around £50,000- on a diamond encrusted Barbie doll for their baby daughter, Blue Ivy's first Birthday according to The Sun.

Specially customised, the doll is said to include 160 diamond gems as well as white gold jewellery. The mega-rich musicians also arranged a lavish princess-themed birthday bash in New York, decorated with £60,000 worth of white and pink roses and a cake costing £1,500.

And the gaggle of toddlers lucky enough to be in Blue Ivy's circle of friends were regaled with £20,000 of accessories and toys including jewellery sets, princess costumes and playhouses.

Meanwhile their wealthy parents were given luxury goodie bags with personalised gold pens with Blue Ivy's name engraved on them as well as sought after concert tickets.

The Crazy In Love singer and her rap star husband are the world's highest paid celebrity couple and last year netted a joint fortune of around $78million in 12 months.

The couple are said to have spent several weeks planning the celebrations for their daughter who turned one last Monday. A source close to the couple said: 'Nothings been too big or expensive for their little princess. They wanted her first birthday to set the tone for the rest of her life.      –DM

They work hard for their money and the first thing they want to spend it on is their baby girl'.
