The irony was not lost as everyone’s childhood hero Bill Nye the Science Guy,  pranced awkwardly around a staged science lab.  The 57-year-old was praised for his enthusiasm and awarded the title ‘Heart of the show,’ by judge Carrie Ann Inaba. 


Glee’s powerhouse singer, Amber Riley, dubbed the Tigress of Season 17, took to the stage in a super fun Cha Cha. In her pre-performance package, she said she hoped she would be an influence: “I think it would be good for young girls to see somebody my size actively trying to dance and throw this weight around.”


Snooki left her fist-pumping back at the Jersey Shore for her first performance, last night.  She held her own toFlo Rida’s ‘Wild Ones,’ and received a ton of technical praise from the judges, fulfilling her wish to prove to everyone that she’s actually not a hot mess.
