This week on “Dancing with the Stars,” Rob Kardashian” and I are dancing the tango to something that I think everyone knows.

People are going to think it’s fun. It’s nice that Monday’s show falls on Halloween night. I feel like every week on the show is Halloween anyway, because we’re always dressing up.

I’m not sure if we’re going to go out after the show and celebrate the holiday because now [we have to prepare] two dances a week, and we’re all so exhausted. I woke up today and I couldn’t move my neck.

I never thought we’d make it this far, but Rob has really proved to everybody that he’s a contender and he knows how to dance. He’s really working hard, and he’s really into it now. The finals could be really hard to get into. That third spot is still up in the air. It could be anyone. Right now it’s like every little thing counts.

Rob is definitely the partner I get along with the most. We just have a lot of fun. There’s not one day that goes by that he doesn’t make me laugh and smile. Normally at this point, you’re tired of each other, but Rob and I never feel that way. We have a great chemistry. We respect each other. We know to have fun with the process.

At the end of the day, it’s hard not to have tension. Sometimes we’ll bicker as normal people do when they work together for so many hours a day, everyday. But I’m really rooting for him and he trusts me, and we have each other’s backs.
