Kate posted videos on Instagram (all four parts) on Friday after being nominated by Dancing With The Stars' Julianne Hough to take part in her #ThanksgivingDanceWars challenge.
Let's just say the ladies know how to do clicks and shimmies in sync. You have to see this.
Now that's how to kick off a boozy Thanksgiving weekend (to the sound of Uptown Funk by Bruno Mars and Mark Ronson).
The videos also star Kate's brothers Oliver Hudson, star of Nashville, Boston Russell and Wyatt Russell as well as her dad, actor Kurt Russell. Check the foot tapping action.
It's all too good, and while there's no sign of Kate's mum Goldie Hawn (she's the camera woman!) you can hear her in the first video counting them in.
It's rowdy, it's raucous and we LOVE it. Man, what we wouldn't give for an invite to theirs this Christmas.
