Princess Carter eats cake! Beyonce and Jay Z's one and only daughter Blue Ivy ate like royalty at her 3rd birthday party this week, as witnessed in a new photo posted to her famous mom's Instagram account on Thursday, Jan. 8.

The sweet snap, taken from above, features the hip-hop scion wearing a frilly pink dress embellished with delicate matching bows. The birthday girl pays no mind to her mom as she's poised with fork-in-hand to devour the brilliant rainbow-colored six-tiered confection.

Blue, who officially turned 3 on Jan. 7, celebrated her birthday with a Frozen-themed party. The world-famous tot's bash included a Queen Elsa-worthy ice sculpture in the shape of a snowflake.

As Us Weekly exclusively revealed in the Jan. 12 issue, Blue is obsessed with Disney's 2013 animated hit. "Frozen is definitely her favorite movie," a source close to the power couple told Us, adding that the little one "always pretends to be Elsa."

And who better to build a snowman with than her loving aunt Solange, who marked Blue's birthday with a sweet social media update this week. "My twin, my fellow sassy pants, my dancing partner, my incredibly smart, beautiful, niece-y-poo, turns 3 today!" Solange wrote alongside a photo with the little one. "I love her so much."
