On Saturday afternoon, “Grease Live” star Vanessa Hudgens was belting out “There Are Worse Things I Could Do” as Pink Lady Rizzo in the final dress rehearsal of Fox’s production of the live musical.

Then Saturday night, she got the news that her father died, which she shared on Twitter.

“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.”

Ever the professional, though, she announced that the show must go on, and she would go ahead with the live performance in his honor.

Fox’s live broadcast of “Grease Live” airs at 7 p.m. PT.
