The Dancing with the Stars premiere on Tuesday evening was memorable, as a dozen of celebrities hit the dance floor for their debut dance on the show.

Here's a recap of the most memorable 'DWTS' moments and videos of the first week of dances.

Judge Bruno Toniloi called transgender contestant and son of Sonny and Cher, Chaz Bono, cute and cuddly.

Courtney Cox sat front row to watch David Arquette do the waltz.

Head judge Len Goodman had only good words to say about J.R. Martinez's performance. For me, J.R. stands for 'Just Right.'

Chynna Phillips scored the highest for a Viennese waltz, tying with Martinez, which Goodman called the best first dance ever on 'DWTS.'

Carson Kressley won the heart of judge Carrie Ann Inaba for her cha-cha.

Rob Kardashian said he was a better dancer than sister Kim, though she scored higher in the first week when she appeared on the show.

Kristin Cavallari kept it safe with a slow, but tricky cha-cha.

Former girlfriend of George Clooney, Elisabetta Canalis began her number on a bed placed on stage.

Ron Artest scored the lowest for a performance with Petra Murgatroyd.

Nancy Grace's cha-cha was not nearly as outspoken as her self-titled television show.

Hope Solo was a bit clumsy at first but resumed grace in her waltz.

Ricki Lake showed off her svelte figure with partner Derek Hough.
