Vanessa Hudgens has dedicated her “Grease Live” performance Sunday night (Jan. 31) to her father, who lost his life on Saturday after battling cancer.

“I am so sad to say that last night my daddy, Greg passed away from stage 4 cancer. Thank you to everyone who kept him in your prayers,” Hudgens tweeted Sunday morning. “Tonight, I do the show in his honor.”

The singer and actress will play the role of Rizzo in “Grease Live” on Fox. She stars alongside Julianne Hough as Sandy and Broadway star Aaron Tveit as Danny. With  “Grease Live” Fox made its debut into the live television musical arena.

The musical will be shown on the television for only one night but it the amount of efforts Fox put into the show since last one year are commendable.

“Our first rehearsal with dancers was in mid-November, and with the full principal cast was Nov. 30 so from then to Jan. 1, we were in the rehearsal studio and then on Jan. 4, we moved here,”  “Grease Live” director Thomas Kail told Variety.

Kail also commended the cast and crew of the musical. “Their learning curve has been very steep,” he told the website. The musical has a runtime of three hours with 23 songs/dances in it. It took the cast more than 52 rehearsals to arrive at the final version.

The first live musical event by Fox will be shot on two sound stages and the Warner Bros. Backlot and built-out exterior locations throughout. The production of the musical gave a new treatment by adding a live audience on set.

The cast also includes Carly Rae Jepsen as Frenchy, Keke Palmer as Marty, “Dancing With The Stars” contestant Carlos Penavega as Kenickie, as well as Mario Lopez, among others.

“Grease Live” aired at 7 Eastern tonight on Fox. Check out relations on Twitter.
