Kourtney Kardashian melts hearts with cute throwback snap of Kylie Jenner: 'Magical little fairy'

Kourtney Kardashian is gushing over her "magical little fairy" sister Kylie Jenner on her special day.

The Lemme founder took to her Instagram account on August 11 to mark her youngest sister Kylie's 29th birthday, while referencing a "Tinker Bell name."

In the celebratory post, the oldest daughter of the Kardashian-Jenner clan shared a throwback snap with Kylie seemingly in her teenage years, while attending a sports event.

In the picture, Kylie can be seen in a white laced tank top paired with green pants, while Kourtney donned casual denim pants with a white graphic tee under a blue coat.

The sweet message on the picture read, "The day you earned your tinker bell name magical little fairy you are."

"Happy birthday sister @kyliejenner," the proud sister added.

Kim Kardashian also posted a heartwarming birthday post for Kylie also sharing throwback snaps from their Keeping Up with the Kardashians days.

In the snaps, young Kylie in a butter yellow dress can be seen sitting on Kim's lap.

"Happy Birthday my princess kitty baby sis @kyliejenner I lovvvveeeeee youuuuuuuuu" Kim penned.

The sweet birthday wishes came after Kylie threw an early birthday bash earlier this weekend with a “Princess Kitty” theme.

All her guests, including her, were wearing pink dresses along with tiaras and featured boas.
