Birthdays are a royal affair when it comes to celebrity couple Jay-Z and Beyonce. And now daughter Blue Ivy is the new part of the tradition. The toddler who turned one Jan.7, not only witnessed a massive princess themed party thrown for her that is said to have cost the couple about $200,000 but also received a diamond encrusted Barbie doll worth $80,000 as a gift. The custom made doll features 160 diamonds as well as white gold jewelry.

Just when we thought that's all, the power couple is also said to have spent an additional $95,000 on pink and white roses, $30,000 on costumes, jewelry and toys for the birthday girl's friends and their parents and $2,400 on the cake.

"Nothing's been too big or expensive for their little princess," The Sun quoted a source. "They wanted her first birthday to set the tone for the rest of her life. They work hard for their money and the first thing they want to spend it on is their baby girl. It's hard to imagine how they can top this next year - or what her Sweet Sixteen will be like."

 The toddler already has her own nursery suite at the New York's Barclays Centre worth $1 million, owns a crystal chair priced at $16,000 and a crib estimated at $20,000.

Blue is also the youngest person ever to feature on a Billboard chart when "Glory" debuted on the chart at number 74. The number includes her cry featured at the end of the song, which also brought her an official credit.

And it's not that the couple splurges only on their little one. Beyonce and Jay-Z have given some very expensive gifts to each other in the past. For Christmas, the rapper gifted the "Single Ladies" hit maker a Hermes Birkin bag worth $350,000 and a private Florida island for $20 million when she turned 29 in 2010.

Beyonce too is famed for showering expensive gifts on the rapper right from a $500,000 sapphire ring and gold rocking horse to a Bugatti Veyron Sport car worth $2 million. When Jay-Z turned 43 in Dec 2012, Beyonce gifted him a $5 million watch adorned with 1282 diamonds.
