Fellow Strictly contestant Victoria Pendleton however has a theory as to why this happened.
Talking exclusively to us at the Twilight premiere earlier this week, Victoria reckons Kim's fans became complacent and thought she would be safe so didn't bother voting.
She told us: "I think there must be a mistake. I think her fans thought she was safe. They won't do that again though I don't think. It was a mistake by her fans."
Talking about this week's Wembley Arena show, Victoria is excited and promises her biggest performance to date.
She explained: "I'm really enjoying it [and] looking forward to the Wembley show just because it will be bigger, a little bit more drama.
"I've got an interesting start to my dance, I've got a big entrance so just wait and see, I hope you like it."

We look forward to seeing what this 'big entrance' is that she's promised us.
It would be safe to say that Victoria has let her nerves get the better of her so far this series with even reigning champion Harry Judd saying she could be amazing if she would just simply keep cool.
Victoria isn't so convinced that it is simply that easy.

She said: "[It's] easier said than done! I just think, 'well I don't really know the steps that well, I've tried to learn them all week but they don't stick,' and then they're like 'Victoria and Brendan doing the...' and you're like, 'oh my gosh!'
"It's really tough to remember!"
Luckily, Victoria has partner Brendan Cole on hand to help her calm those pesky nerves.
"He's just a very calm person, he loves show day. His love for show day definitely helps me because he's just like, 'go out there and enjoy it, it's amazing it's a rare opportunity' so I'm like, 'yes you're right', he talks a lot of sense on show days," she explained.
And as for whom she thinks will win the series? Well Victoria is backing her fellow Olympian Louis Smith to take the title.
She admitted: "I'm all about Louis. I think Louis has got it down. He is so good at learning routines and he looks amazing. He's loving it, I've got to support my fellow Olympian there. Go Louis!"
