Kim Kardashian wore her go-to Balenciaga catsuits on Jimmy Fallon's show!

During Jimmy Fallon's The Tonight Show, Kim Kardashian snuggled up with her kids Saint West, 6, and Psalm West, 3.

In one picture, Psalm stuck his tongue out and made a humorous face while having fun with Saint.

She wore her bleach blonde hair down and long in a loosely wavy blowout, while still rocking her bleach blonde hair from the Met Gala in early May.

In her go-to Balenciaga pant-boot cat suit, she wore a silver Balenciaga Le Cagole bag over her shoulder with no jewelry.

It turns out their wild energy also made it onto air: Kim stopped the hat to quiet Saint and Psalm.

During Jimmy's explanation, the boys were sitting off stage with Tracy Romulus' daughter Remi.

Kim said 'Guys, this is your first time at work with me. Don't mess this up. Come on' as Psalm was taken backstage.

Saint wore dark jeans and a brown NY Yankees hat over Jack's jersey-inspired shirt.
