Beyoncé's performance at Coachella made entertainment history as the first black women to headline the event. As fans and fellow performers alike have been showering the iconic performer with praise, this 'Glee' actor joined the conversation.

Harry Shum Jr.—who played Mike Chang on 'Glee'—took to Twitter to say, "One of my greatest memories as a dancer was watching @Beyonce work during rehearsals. She knew every misstep that happened on stage & expected greatness from everyone. Usually the dancers are hired to lift up the artist but on tour, we had to keep up with her. #stillkillinit"
