Kim Kardashian is giving fans a glimpse into her son Saint West's third birthday party.

The 38-year-old "Keeping Up with the Kardashians" star celebrated the occasion at a Tarzan-themed bash with husband Kanye West, their daughters, 5-year-old North and 10-month-old Chicago, and other family and friends.

Kardashian posted a slideshow of photos Tuesday of herself and her family at the fete.

Saint wears a camouflage-printed outfit, while North sports a bright green ensemble.

"Celebrating Saint with a Tarzan themed party," Kardashian captioned the post.

People said Kardashian threw the party at her home Dec. 1 in honor of Saint and Reign Disick, the younger son of Kardashian's sister Kourtney Kardashian.

The cousins celebrated at a joint Monsters, Inc.-themed bash the year previous.

Saint officially turned three years old Dec. 5. Kardashian and her mom, Kris Jenner, were among those to wish Saint a happy birthday online.
