Cheryl Burke has penned a new blog at People.com. She writes about the “brother-sister relationship” she has with her partner Rob Kardashian. They bicker and ‘literally’ throw punches, but, she feels comfortable with him and he brings out the funny side of her. More below and at the link on the journey so far.

I’m happy I’m dancing with Rob. Every person I dance with is a whole different experience. But I can definitely tell that this one with Rob is going to be the most memorable for sure. We’re just really good friends. I’ve known Rob from before the show started. We used to hang out all the time, so it’s kind of like I’ve never trained anyone that I knew already.

He’s pretty good. He’s really fast on his feet and he loves just having fun with the whole thing. He doesn’t make fun of the dance, but he really brings out the lighter side of himself.

When it comes to personality, he’s really funny. He’s so sweet. I kind of thought he was going to be stuck-up, maybe and immature, but he’s opposite. He’s so sweet, he’s so charming, and he’s so funny. He has this dry, sarcastic sense of humor, so in the beginning, I wasn’t sure if he was joking or being honest, but he’s funny and he knows how to take things seriously as well though.

We’re both not nervous yet for the first night of the show. But I think once we have our first rehearsal on stage, it might bring out his nervous side. But I think for now, we’re really just a good match. I told him to just smile and have fun.
