"Grease: Live" is already becoming a sensation, at least based on the Internet reaction.

And a lot of it has to do with star Vanessa Hudgens.

The actress performed Sunday night just hours after announcing the death of her father from stage-four cancer. She posted about his passing away last night on Twitter. Rather than canceling her performance, she continued and dedicated the show to him.

The Fox live show is a recreation of the popular musical that was made into the 1978 film starring John Travolta and Olivia Newton-John. Hudgens plays Rizzo in a cast that includes Julianne Hough, Aaron Tveit, Carly Rae Jepsen, and Joe Jonas.

Many viewers thought Hudgens knocked her version of the difficult song "There Are Worse Things (I Could Do)" out of the park, especially under the extremely difficult circumstances.
