Hudgens' father was in the hospital during rehearsals for Grease: Live. The 27-year-old actress rose to fame by way of Disney's "High School Musical"; she made her Broadway debut as the title role in Gigi, and tonight she will star as Rizzo in Grease.
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.
Tonight, I do the show in his honor.
