ABC News’ Amanda Keegan reports:

 

Ricki Lake rose to the top of the leader board this week with a super-high-energy jive, while Chaz Bono tumbled down to the bottom, all thanks to a leg injury. 

 

Kristin Cavallari wowed judges with her Marilyn Monroe-style quickstep – making her one of the contestants to watch out for. Fan favorite J.R. Martinez tied with her for second, despite Len’s complaint that he danced more of a lindy hop than a  jive.

Insecurities seemed to get the best of some of the contestants during rehearsals. Rob Kardashian complained about his “man boobs,” while Nancy Grace, still upset from her disappointing cha-cha performance last week, was reduced to tears while trying to learn the quickstep (and she suffered a wardrobe malfunction when a nipple was partially exposed at the end of her performance.)

Grace and Kardashian performed well, ending in a three-way tie with Chynna Phillips for third place.  Judge Carrie Ann Inaba also proclaimed Rob Kardashian ”a better dancer” than his famous sister and former contestant, Kim Kardashian.

Courtney Arquette was in the audience yet again to cheer on Arquette. Their daughter, Coco, was the lucky one to catch Arquette’s coat at the end of his performance.  Bruce and Kris Jenner were there to support Kardashian, and past “Dancing With the Stars” contestant Rick Fox was there with his girlfriend Eliza Dushku.

Overall, a great night of performances, but looks like Chaz will be in the hot seat Tuesday.
