They've got to keep up the action for their show!

Kris Jenner, Khloe Kardashian and Scott Disick hit the tracks to race go-karts yesterday while the cameras rolled for Keeping Up with Kardashians, and you know that if E! wasn't paying her for this, Kris would rather be off making money elsewhere.

It's a little surprising The Lord joined in on the fun, considering girlfriend Kourtney just gave birth to their third child. We're dying to know their little boy's name! Let's hope they didn't take a page from Kimye's book and name him something completely absurd!
