Kim attended the game with her son Saint for his birthday, and he is known to be a huge sports fan.

He was seen wearing a Number 23 Lakers jersey, the number of basketball superstar LeBron James.

The Skims founder was sporting an all-black outfit with a tight and low-cut top that pushed her cleavage together.

In addition to her all-black attire, she added a bit of sparkle with her unique clutch.

Instead of a typical rectangular purse, Kim was carrying a silver rhinestone bag that looked like a high heel.

WHY KIM, WHY?

Once fans were made aware of The Kardashians star’s presence at the game, X, formerly known as Twitter, went wild.

One aggressive Lakers fan said: “Kim Kardashian’s stupid annoying a** being courtside looking bored as f**k is pissing me off.

“If you don’t cheer for the #Lakeshow right now … Yes, I’m bitter.”

Another person had a similar complaint, writing: “Kim Kardashian wasting them front row seats all in her d**n phone lol.”

A third said: “FYI: there is Kim Kardashian in the background texting while everyone else is freaking out at Anthony Davis‘s DUNK!!”

“Kim Kardashian, why are you even at the Lakers game? You’re missing out on the action. #GoHome,” a fourth person wrote while including a picture of Kim on her phone.

However, others were star-struck to see the celeb, with one person tweeting a video of Kim and Saint waving.

“KIM KARDASHIAN IS IN THE BUILDING,” the tweet read.

“Kim Kardashian come to the Lakers game for the rest of the season plz,” read another tweet.

“I’ll be at the game in January. I’ll save you a seat Kim Kardashian,” read a third.

Kim is known to bring Saint around the globe to attend professional soccer games together.

In late July, the mother-son duo traveled to Japan to watch the Paris Saint-Germain vs. Al-Nassr FC match.

SAINT’S BIRTHDAY

Kim’s surprise appearance at the Lakers game came as the family celebrated Saint’s birthday on December 5.

Kris Jenner took to her Instagram Stories on Tuesday to honor her grandson and show some appreciation to his mom.

“Happy birthday our amazing Sainty!!!!! Your smile and your spirit and your heart just keep getting bigger and bigger!” she wrote in the caption.

She posted a carousel of photos with several snaps of Saint that summed up his life so far.

The Kar-Jenner matriarch showed moments of Saint as a baby, and when he was a toddler.

There were also family photos of Saint with Kim, 43, Kris, and his other siblings North, 10, Psalm, 4, and Chicago, 5.
