It's Hollywood night this week on 'Dancing with the Stars.' The contestants had to wrap their heads around the idea of traditional ballroom moves. From foxtrot and quickstep to rhumba and charleston, the night was a bit of a challenge for some of the celebrities because this meant they really had to jump into the ballroom world headfirst -- and for most of them, it was their first time.

Whether it was influence from 'The Great Gatsby' or the James Bond films, the stars and pro dancers brought out the high energy and fun. Corbin Blue and Brant Daugherty from 'Pretty Little Liars' may have entertained with their own quickstep routines, however, Nicole "Snooki" Polizzi gave a memorable performance by channeling her inner Marilyn Monroe with her partner, Sasha Farber, when they danced to 'Diamonds Are a Girl's Best Friend.' Not only was she determined to do better than getting a rating of "6" from the judges, she and Sasha pulled off a quick one-handed cartwheel that wowed the crowd.

Amber Riley and Christina Milian showed off their playful sides with the charleston. Although both contestants received good scores, they were both critiqued on their feet and technique on some of the choreography.

While the show was supposed to be light and fun, things turned a bit serious (and slightly dramatic) for Bill Nye. The 'Science Guy' injured a tendon and was initially not allowed to dance. However, he and his partner, Tyne Stecklein, tweaked their routine and pulled off a futuristic set to Daft Punk's 'Get Lucky.'

Unfortunately, Nye's robot was just not enough to keep him on another week and he becomes the second celeb to get eliminated. Milian also has a few things to worry about for the next week as she was in the bottom two with Nye. Hopefully, her charleston routine and clips of her daughter during rehearsal will warm fans' hearts enough to keep her on the show for another week.
