Saint West is following in his mom's fashion footsteps.

Kim Kardashian, who's been known to enter her blonde era from time to time, showed off the 8-year-old's golden during his birthday outing to see the Los Angeles Lakers take on the Phoenix Suns.

The SKIMS cofounder snapped a sweet courtside selfie with Saint at the Dec. 5 basketball game, where her second-oldest was rocking his new ‘do and donning a LeBron James jersey.

"My twin Sainto," she captioned the heartfelt birthday post, which also featured several wholesome throwback pics and videos of Saint. "How are you 8 years old already! I just love you so so so much!"

But Kim—who along with Saint shares kids North, 10, Chicago, 5, and Psalm, 4, with ex Kanye West—wasn't the only Kardashian-Jenner to celebrate his birthday on social media. In fact, Grandma Kris Jenner posted a heartfelt message alongside her carousel of photos.
