Grease is the word! Grease: Live aired on Fox Sunday, January 31, and social media basically exploded from the excitement.

Hudgens, 27, wowed with her performance as Rizzo — a feat she bravely pulled off just one day after the death of her father, Greg, from cancer.

She received an outpouring of support from fans and friends, including Ashley Tisdale, who was so “proud” of her High School Musical costar.

On a much lighter note, many viewers, including Anna Kendrick, just couldn’t stop staring at Aaron Tveit’s extremely short shorts. The Broadway veteran sported the teeny-tiny shorts while walking around Rydell High’s gym, which instantly became a talking point on social media.
