FOX's Grease Live has special meaning for one star

Tonight's performance of Grease Live on FOX will have a special meaning for one member of the cast.

Actress Vanessa Hudgens, 27, tweeted Sunday that, after a battle with stage 4 cancer, her father had passed away.

She then added, "Tonight, I do the show in his honor."

Greg Hudgens' diagnosis was first revealed by his daughter in August of 2015.

Hudgens will be playing the role of Betty Rizzo alongside actress Julianne Hough and actor Aaron Tveit in the musical performance. The show airs live on FOX at 7 p.m. Eastern Time.
