Vanessa Hudgens loses dad to cancer hours before 'Grease: Live' performance

The show must go on. That's the message from Vanessa Hudgens, who performed in "Grease: Live" Sunday night - just hours after finding out her father died.

The 27-year-old said on Twitter Sunday morning that her father, Greg Hudgens, died after battling stage 4 cancer. He was 65 years old.

Vanessa had revealed his ailment last August, according to E! Online.

"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 the sad announcement hours before FOX's Grease: Live musical special.

"Tonight, I will do the show in his honor," she wrote.

Hudgens, who's playing Rizzo in FOX's production of the popular movie musical, dedicated her performance to her dad.
