The reality star shared a sweet pic of her 'beautiful boy' rockin' cornrows and blue jeans.

Happy Birthday, Saint West!

Kim Kardashian West and Kanye West's son turned two on Tuesday, and in honor of his special day, his famous mama shared a sweet photo of him to Instagram as part of her 25 Days of Christmas photo series.

Kim's "Day 5" post featured little Saint shirtless, rocking cornrows and a pair of blue jeans.

"HAPPY BIRTHDAY to my beautiful boy Saint!" she captioned it. "I love you so much! You don't even understand!!!"

This is the second time that Saint's been featured in the series, which will ultimately reveal the Kardashian-Jenner's annual Christmas card. His older sister, 4-year-old North, was the center of attention in Kim's "Day 4" post, looking oh-so cute in a white tank top, denim jacket and jeans that matched her mother's ensemble.

Kim has been keeping busy ahead of the upcoming holiday. In addition to her photo series, the mother of two has also been making a few festive appearances, her latest at the The Tot holiday pop-up celebration at Laduree at the Grove in Los Angeles on Monday. 

The Selfish author flaunted her enviable abs in a skintight silver cutout dress, which perfectly matched her new, icy blond 'do.

While speaking to ET last month, Kim revealed that she was in charge of the family's holiday card this year.

"I'll never do it again," she joked. "Just to wrangle every single family member was so exhausting. I thought it would be really easy. It was really tough. But it'll be a good one this year, I think our best yet."

"It definitely gave me a little bit of anxiety with all the kids running around just thinking, 'Holy sh*t. How am I going to do three kids?' I'm really freaking out," she added. "It was kind of a freak-out moment for me."
