Kate's mother, Oscar-winning actress Goldie Hawn, can be heartd counting the group in before Kate and Cara jump out from behind a set of curtains. Sitting on the sofa in the foreground are Kate's brother Oliver Hudson, Goldie's long-term partner Kurt Russell, his son Boston Russell and his with Goldie, Wyatt Russell.
"We gladly accept @juleshough #thanksgivingdancewars challenge," posted Kate. "Let's make this happen @caradelevingne #oliverhudson #wyattrussell #bostonrussell #pa #dancebattle #UptownFunk And that's my Mom counting us in in the background."
Clearly thrilled to be celebrating the holiday in the US, London-born Cara thanked her hosts.
"First and best thanksgiving ever!" wrote Cara on Instagram. "Thank you @katehudson and family #thanksgivingdancewars @juleshough thanks for the count in Goldie."
Shortly after the festive celebration, however, Cara was off seeing more of her famous friends.
The 22-year-old joined reality star Kendall Jenner, model Gigi Hadid and Australian singer Cody Simpson at Disneyland in Anaheim, California.
