"Glee" actress Amber Riley became the surprise "Tigress" of the new season with her Cha-Cha, performed with professional dancer, Derek Hough. She earned the highest points of the night, with a near perfect score of 27 (all 9s from the 3 judges).

However, there was another performance that left the audience in tears- that of actress Valerie Harper, who was diagnosed with brain cancer earlier this year, danced the Fox Trot.
