The SKIMS founder, 43, shares Saint as well as North, 10, Chicago, five, and Psalm, four, with ex-husband Kanye West, 46.

Kim transformed the backyard of her $60 million mansion into a soccer player’s paradise.

Kim Kardashian shared behind-the-scenes photos and videos from her son Saint West’s eighth birthday party

Saint loves soccer and his mom threw a soccer-themed party for her eldest son

Saint and his friends ran around the backyard which was filled with several bounce houses as well as setups that helped them work on their soccer skills such as kicking and goal scoring.

But when it came to the cake, the American Horror Story: Delicate star revealed: ‘Fun fact- Saint hates cake so @butterloveandhardwork made an all chocolate soccer ball instead of a cake! The kids loved it!’

She then shared a video of Saint taking a mallet to the soccer ball to smash it and reveal the soccer ball chocolates inside.

All of the party guests also received a unique gift – a white Adidas soccer jersey with ‘Best in the West’ on the front and Saint’s name and the number eight on the back.

The food at the party kept with the theme. Grilled cheese sandwiches were printed to look like soccer balls, other foods like French fries were put in soccer ball printed bags.

On Saint’s birthday, the mom of four also shared a tribute to her son on Instagram.

‘My twin Sainto! How are you 8 years old already! I just love you so so so much!’ she wrote in her caption next to several photos and videos of Saint — including an adorable throwback shot from when he was a baby.

She posted a side by side image with a photo of her as a baby and one of Saint as a newborn and the two do look like the same person.

Even the cake — which wasn’t actually a cake — was in the shape of a larger-than-life soccer ball.

The kids gathered excitedly to watch the birthday boy break into the ‘cake’

The proud mom also showed off a short video clip of her youngest child, son Psalm.

In the snap, the tot’s hair was freshly buzzed close to his skull.

‘Does anybody recognize this boy?’ she jokingly said as she approached her son.

Psalm kept in theme for his big brother’s party in a soccer jersey and shorts.
