Vanessa Hudgens revealed that her father Greg Hudgens is battling cancer at the 2015 Industry Dance Awards & Cancer Benefit Show.

The "High School Musical" actress arrived at the charity awards at Avalon in Hollywood with boyfriend Austin Butler, who lost his mother to cancer in 2014.

"Last year, my boyfriend, Austin [Butler], lost his mom, Lori, to cancer, and my dad has just been recently diagnosed with stage-four cancer. And let me tell you, I hate cancer. I hate cancer with every cell of my being," said an emotional Vanessa as she received the award for the Breakthrough Performer.

The proceeds from the charity event will go to The Circle of Hope, and organization that is dedicated to supporting dancers who have survived cancer.

A few weeks ago, Vanessa had posted on Instagram that her father was in ill but did not disclose the disease, just saying, "Please pray for his healing!!! The more prayers the better."

However, at the awards, she opened up even more and said, "If you would have asked me two years ago what I thought of cancer I would have said, 'Man, you know, it sucks, it's a horrible disease.' But that's only because I had not been faced with it personally."

Vanessa told the audience that she and her boyfriend know how it is like to deal with the grim disease as a family.

"This award, it means a lot to me but I dedicate it to my boyfriend's mom ... Lori, my dad, and to all the families out there who are struggling with this because it really takes a strong person and a strong family to be able to help those out who are going through this," she continued.
