OTRC: Nancy Grace: 'Kardashian Butt' boosted Rob on 'DWTS' (Video)

Nancy Grace talks to OnTheRedCarpet.com after the finale of 'Dancing With The Stars' on Nov. 22, 2011.

Nancy Grace has a theory about why her fellow "Dancing With The Stars" contestants Rob Kardashian, J.R. Martinez and Ricki Lake beat her to make it to the finals.

The 52-year-old outspoken legal commentator, who hosts her own HLN show, and partner Tristan MacManus placed fifth during the recent 13th season of the ABC ballroom dancing show. Martinez, an Iraq war veteran and former soap opera star, and Karina Smirnoff were named the winners on Tuesday, November 22.

"Here's the breakdown," Grace told OnTheRedCarpet.com after the show. "Ricki is such a fantastic dancer. She is a professional dancer. You can't really beat that. Then there was Kardashian - he had the whole Kardashian Tweet Empire and the Kardasian Butt in his favor. And then J.R., the war hero, who can dance. Let's see. Kardashian Butt, war hero, Kardashian Butt, war hero.."

Rob Kardashian was often ... the butt of friendly jokes on "Dancing With The Stars" due to his own behind, which he dubbed his "secret weapons," but it is his sister Kim who is more famous for her own curvy, pear-shaped figure. Both appear on the E! reality show "Keeping Up With The Kardashians." Their co-stars and siblings often rallied their Twitter followers to vote for their brother to advance on "Dancing With The Stars" and also sat among the studio audience to cheer him on.

Rob Kardashian and partner Cheryl Burke placed second. Lake. who is known for her 1990s talk show and for her starring role in the original 1988 "Hairspray" film, came in third with partner Derek Hough.

Kim Kardashian, who is currently going through her second divorce, has also competed on "Dancing With The Stars" herself. The reality actress was the third celebrity to be eliminated during the 7th season in 2008, following actor Ted McGinley.

The show's 14th season is set to premiere on March 19, 2012. Check out photos of past winners of "Dancing WithThe Stars."
