Rob Kardashian may have some of the most famous sisters on the planet, but he is stepping out into the limelight on his own as a member of the newest lineup of Dancing with Stars season 13. Following in his big sis Kim’s footsteps–she participated in the show’s seventh season in 2008–Rob is hoping to fare a bit better, telling Us Weekly, “I don’t want her advice. I don’t need advice from someone who lasted, I think three weeks.” Wow–that’s some fierce sibling rivalry! Additionally, he’s hoping to get svelte during the stint as he is feeling less than confident about his physique. “I really want to get into shape. You probably wouldn’t know, but I’m the most insecure and overweight I’ve ever been,” he admitted to the magazine.  “I’m over 200 pounds, so I want to drop weight and this will be a good start.”

He’s not alone in turning to “Dancing” to help slim down. Last season, celebs including Wendy Williams, Kendra Wilkinson, and Kirstie Alley also looked to the contest’s rigorous routines to help them shed the pounds. And Ricki Lake, one of Rob’s 11 competitors this season, said that she’s hoping to firm up on the dance floor as well. “I fell in love and I got a little fluffy this year,” the 42-year-old former talk show host told Access Hollywood Live. “This is definitely time for me to shed the [pounds] for my wedding next year.” Other contestants joining Rob this season include David Arquette, Chaz Bono, and Kristin Cavallari. The new season should be a doosie, but in the meantime, Rob’s looking rather fresh in these sleek Persol wayfarer eyeglasses. -rpuccia
