Last week Rob Kardashian poked fun at his own jiggling man boobs. This week during his Foxtrot for his father, the Dancing With the Stars Season 13 celeb looked dashing and debonair.

There’s no doubt about it: Rob’s confidence is up, big time. His partner, Cheryl Burke, sees a big change in him, from his physical appearance to his attitude.

“He's lost a lot of weight,” Cheryl wrote in her People.com blog. “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.”

In terms of his changing attitude, getting praise from the judges last week certainly helped — including Carrie Ann Inaba’s announcement that Rob is a better dancer than his sister, Kim Kardashian.

“It's just nice to hear positive feedback, especially for Rob,” Cheryl wrote. “He does have his insecurities and he does have low self-confidence. I think it really pushed him to do even better this week.”

Rob had the first dance of Week 3 and got his best score to date, a 24 out of 30, for his Foxtrot. He started the season with a 16, then a 21 and now he’s in a strong position with the rest of the pack. He is definitely a better dancer than Kim and he’s showing a bit more personality out on the ballroom floor, even if he still says dumb things off the dance floor. Considering he does have the largest fan base out there — no one comes close to his 2,000,000-plus Twitter followers — he could conceivably ride the DWTS train all the way to the finals.
