Blue Ivy Carter, whose parents are mega-star Beyonce Knowles and Sean "Jay-Z" Carter, celebrated her first birthday with an over-the-top birthday bash on Monday, Jan.7.

The power couple spent a cool $200,000 on a party for their only child. No expense was spared when they spent a whopping $90,000 on white and pink roses for decorations and over $2,000 for her birthday cake.

They also spent a fortune on gifts for the young guests as well as the adults who attended. Children were treated to gift bags that included jewelry sets, princess costumes and doll houses while the adults were spoiled with goodie bags that contained expensive booty, including tickets to concerts at the Barclays Center in Brooklyn and personalized pens with their individual names and Blue Ivy's name engraved on it.

Not surprisingly, their largest expense went on their gift for the birthday girl. The parents gave their daughter a diamond-encrusted Barbie doll that cost a whopping $80,000!

The customized doll has 160 diamonds and white gold jewelry on it, according to a report.

A source close to the couple said nothing "is too big or expensive for their little princess."

"They wanted her first birthday to set the tone for the rest of her life," the insider told The Sun. "They work hard for their money and the first thing they want to spend it on is their baby girl.

The insider said it was "hard to imagine how they can top this next year," but not before adding that they can't imagine what Blue Ivy's "Sweet Sixteen" will be like.

Enstarz reported on on Jan. 7 that Blue Ivy spends her time at the the most expensive suite at Brooklyn's Barclay Center. Her rapper father spends $1 million a year for a private suite on the basement level that is a luxury nursery and sometimes doubles as a VIP lounge for his close pals.

The expenses on Blue Ivy may not come as a shock to some - the married couple were dubbed Forbes' Richest Celebrity Couple of 2012 for having earned a combined $78 million last year before Beyonce garnered a $50 million Pepsi deal in December.
