Luckiest little girl ever? Beyoncé and Jay Z threw their daughter, Bluethe ultimate fourth birthday party — and it might be the fanciest, prettiest kids' party ever. Blue turned 4 on January 7, but her famous mom just shared new photos from the extravagant bash on her website on Tuesday, April 12.

Blue's fairy-theme, flowery celebration was held at a lavish estate, outside in the warm weather. In the sumptuous shots, the birthday girl and her loved ones roamed free underneath a large clear tent during the festivities. Underneath the canvas, guests played in two smaller white tents and lounged on couches and floor pillows.

Rounding out the festive decor were balloons, twinkling lights and rose bouquets hanging from the ceiling.

Wee revelers also hung out at a dress-up station, where Queen Bey and Jay Z's only child tried on costumes, a crown and pink fairy wings.

Last year, Blue celebrated her third birthday with a Frozen-theme bash featuring a rainbow tiered cake. "Frozen is definitely her favorite movie.… [She] watches it several times a day," a source previously told Us Weekly. "Blue always pretends to be Elsa."
