The actress hosted the 2014 Entertainment Industry Foundation's Revlon Run/Walk for Women in New York City Saturday, sharing her duties with Bravo exec/Watch What Happens Live host Andy Cohen. While she was there, Emma talked about her mother's battle with breast cancer.
"My mom, she's always been my hero," Emma said, according to ABC News. "Watching her experience something like breast cancer was pivotal, I think in my whole family's life and experience. She is one strong lady, so we are walking together today. It's pretty great thing to be here five years later."
This is the third year the 25-year-old star has been involved with the event, adding, "I just am a big fan of this event and it's so inspirational and there's so much energy. They've done so much to give back."
"As an actor, I end up talking about movies that I'm a part of, which is great," she continued, "but to be able to talk about something that can really make some fundamental change in terms of – I can't cure cancer, or treat it – but the fact that I can be part of something that really is able to give back in such a major way is a big honor."
Emma has also been candid in the past about her mother's battle with breast cancer, saying last may that she was "terrified" when her mother was diagnosed with triple negative breast cancer in 2008.
"I was oddly stoic, the opposite of how I usually am. But it was terrifying," Emma said.
Her mom, Krista, was 48 when she was diagnosed with the highly aggressive breast cancer. At the time Emma was 19 and living alone in Los Angeles, and would fly back and forth to Arizona to be with her mom while she was undergoing chemotherapy and recovering from a double mastectomy.
