The 27-year-old High School Musical alum brought the house down with her stunning, sassy performance as Betty Rizzo, which she dedicated to her late father, who died Saturday after a long battle with cancer.
Hudgens, who was part of a star-studded cast that included Julianne Hough, Aaron Tveit, Carly Rae Jepsen, Carlos PenaVega and Keke Palmer, showed off her acting chops yet again by perfectly embodying the spirit of the beloved character.
Additionally, her powerful and captivating performance of "There Are Worse Things I Could Do" set the bar for solo numbers in the entire production.
Even in the face of personal tragedy, Hudgens' smile, her laugh and her delivery never faltered for even a moment, and she added some extra spark to the already dazzling display.
In the final moments of the broadcast, the show honored her father in the credits with a special chyron reading, "In loving memory of Greg Hudgens."
Even in the hours leading up to her father's passing, Hudgens was the epitome of a performance professional.
ETonline was in the live studio audience during Saturday's Grease: Live! dress rehearsal, and you would never know that Hudgens was dealing with a personal tragedy. In between takes, the former Disney darling stayed in character as the sharp-tongued Rizzo, and she was all smiles even when the cameras weren't rolling.
Hudgens revealed the news of her dad's death on Twitter hours before the show was set to kick off.
"I am so sad to say that last night my daddy, Greg passed away from stage 4 cancer," she wrote, which was retweeted by her 20-year-old sister, Stella Hudgens. "Thank you to everyone who kept him in your prayers."
