Last night (Jan. 31), Vanessa Hudgens reminded everyone why she is the ultimate singing queen after giving a spectacular performance as leader of the Pink Ladies, Betty Rizzo, on "Grease: Live." She, along with fellow costars Aaron Tveit, Julianne Hough, Keke Palmer and Carly Rae Jepsen, wowed audiences and brought the music and story of "Grease" back into the forefront of people's minds.

However, Hudgens' performance was extra special (and heart-wrenching) because her father, Greg, had just died the day before. The former "High School Musical" star announced his passing on Twitter and explained her performance would be done "in his honor."

Even though she was undeniably mourning the loss of her father, she didn't let her grief slow her down. As the old saying goes, "The show must go on." The Twittersphere was abuzz with positive tweets and comments about "Grease: Live," especially with regards to what Hudgens brought to the table. Several celebs simultaneously shared their congratulations and condolences to the 27-year-old actress.

But probably the sweetest praise she's been given is from her own boyfriend, "The Shannara Chronicles" actor Austin Butler.

The production included a heartwarming dedication to Hudgens' father at the end of the show.

If you missed "Grease: Live" here's a snippet of why everyone is freaking out and praising Hudgens right and left. She definitely deserves every compliment she receives.

Congrats on all your success, Vanessa. You father would indeed be very proud of you.
