After Vanessa Hudgens’ Dad Dies, ‘Grease: Live’ Star Has ‘Hysterical Breakdown’ Backstage Following Performance: Report

“High School Musical” star Vanessa Hudgens proved the show must go on when she performed in Fox’s “Grease: Live” Sunday, a day after her father, Greg Hudgens, died of stage 4 cancer. While the star was able to push on through the show, she had a “hysterical breakdown” backstage, Radar Online wrote in an exclusive report Monday.

“Of course, she was crying after the show wrapped,” a source told Radar Online. “But she was just surrounded by so much love and support that everyone knows she will get through this.” The unidentified source added, “Everyone was really trying to just make sure that she was OK.”

Hudgens, 27, went through with the performance because her father loved “Grease” and would have wanted to see her play Rizzo in the live-television version of the classic film and theatrical production. “She had to make him proud,” the source said. “She insisted on still doing this because her dad would want nothing [less].”

The star tweeted about her father’s death hours before she took the stage. “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. “Tonight, I do the show in his honor.”

Her sister, Stella Hudgens, also tweeted about their father’s death:

And when Vanessa Hudgens was finished with her performance, her sister praised the multitalented entertainer. “TEARS. everywhere. @VanessaHudgens you are just unbelievable. #GreaseLive,” she wrote.

Vanessa Hudgens revealed her father was diagnosed with cancer when she was honored at the 2015 Industry Dance Awards show in August. “My dad has just been recently diagnosed with stage 4 cancer,” she said at the time. “Let me tell you, I hate cancer. I hate cancer with every cell of my being.”
