Miley Cyrus just joined the long list of philanthropic celebrities rushing to aid Hurricane Harvey victims, and got real emotional about it on "Ellen" Wednesday.

The pop star donated half a million dollars via her organization, The Happy Hippie Foundation, and was brought to tears when Ellen DeGeneres brought up the act of kindness.

"I can't really talk about it. I don't know why it makes me so upset," Cyrus said tearfully in the video (above). "I really hope people know -- I'm not even, like I couldn't fake it. My grandma's sitting here and my mom's here and I go home to my seven dogs, and if I didn't have that anymore, it'd just be really hard, so I'm really happy to help in any way that I can."

"And I hope people understand and can put themselves in those people's shoes and know what it feels like to have everything taken away from you," Cyrus added.

Leonardo Di Caprio also pledged on Wednesday that he'd be donating $1 million to the newly established United Way Harvey Recovery Fund via The Leonardo DiCaprio Foundation.

The list of stars who have publicly made pledges to Hurricane Harvey relief now includes Cyrus, DiCaprio, Sandra Bullock, Kim Kardashian, Khloe Kardashian, Kourtney Kardashian Kris Jenner, Kendall Jenner, Kylie Jenner Jennifer Lopez, Alex Rodriguez, Jensen Ackles, Chris Young, Kandi Burruss, T.I., Chris Paul, Nicki Minaj, Chris Brown, The Chainsmokers, DJ Khaled, Wendy Williams, Kevin Hart and Dwayne "The Rock" Johnson.

Beyoncé told the Houston Chronicle that she and her team are currently working on a plan to help as many people in her hometown as possible.

"My heart goes out to my hometown, Houston, and I remain in constant prayer for those affected and for the rescuers who have been so brave and determined to do so much to help," she said. "I am working closely with my team at BeyGOOD as well as my pastor (Rudy Rasmus at St. John's in downtown Houston) to implement a plan to help as many as we can."
