Khloe and Kris were filming for the new series of Keeping Up With The Kardashians when they decided to head down to MB2 Racing in Los Angeles.
And, not wanting to miss out on all of the fun, Scott Disick - Kourtney Kardashian's long-term partner - joined them after feeling a need for some speed.
Posting a snap of herself and her mum Kris on Instagram, Khloe told her followers: "Vroom vroooooooommmmmmm."
Earlier in the day, Khloe was photographed arriving at MB2 Racing and we are pretty impressed with how glamorous she looked considering what she was about to do!
While most of us would wear trainers and jogging bottoms to drive a go-kart, Khloe was snapped outside the venue in a long black cardigan, light blue jeans and knee-high boots.
The US reality star was toting a designer bag, wearing a smart pair of aviators and had her long ombre hair styled in beachy waves.
Well, they do say Formula 1 is one of the most glam sports in the world!
Meanwhile, on Sunday Khloe's sister Kourtney gave birth to hers and Scott's third child together, a baby boy.
The tot's arrival actually fell on their eldest son Mason's fifth birthday. Kourtney and Scott are also parents to two-year-old daughter Penelope.
We're quite surprised to hear Scott was also go-karting yesterday, but perhaps he already felt the need for a break from nappies and crying...?
