The build-up to Vanessa Hudgens playing Rizzo in Grease has been coming up fast.

"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," she wrote on social media.

And she did just that.

As the actors and actresses took a bow in front of the Grease Ferris wheel, a message came up at the bottom of the screen. 

"In loving memory of Greg Hudgens. June 22, 1950 – January 30, 2016," the tribute read.

And Vanessa's long-time BFF, Ashley Tisdale was supporting here friend all the way though.

"There's My Girl @VanessaHudgens!!! #GreaseLive," she wrote on Twitter.
