Vanessa Hudgens is mourning the loss of her father, hours before she is set to take the stage in an anticipated live musical production.

"I am so sad to say that last night my daddy, Greg passed away from stage 4 cancer," she wrote. "Thank you to everyone who kept him in your prayers."
Vanessa made her sad announcement hours before FOX's Grease: Live musical special. The program airs at 7 p.m. ET.
Vanessa plays Rizzo in the production.
"Tonight, I do the show in his honor," she tweeted.
In addition to the actress, Greg is also survived by her mother and his wife Gina Hudgens and Vanessa's 20-year-old sister Stella Hudgens.
