Cheryl Burke has been partnered with Rob Kardashian on this season of "Dancing with the Stars," and she is singing his praises.
In a special piece on PEOPLE.com this week, Burke commented about Kardashian's performance thus far and his weight loss. Burke said in the piece, "I can tell Rob is getting more comfortable with his body because he's starting to wear tank tops to rehearsals. And you'll see his arms out. In the beginning, you'd never see that. He looks at himself in the mirror. It's really cute."
Burke also commented, "[Rob's] lost a lot of weight. His whole physical appearance has changed. He's using different muscles. He's super sore all the time. I'm not sure if he's changing his diet, but the cardio is really good. I think he lost most of the weight just rehearsing from the jive because it's so fast-paced."
When commenting about this week's performance, Burke said, "This week we're doing the foxtrot, and the theme for the couples is 'most memorable year of your life.' It's a very touching and really sweet story that Rob is telling. People will see more of the sensitive side, and how family-oriented Rob is."
Burke and Kardashian performed the foxtrot during Monday's episode. You can check out their performance below.
