Fifth Harmony star Normani Kordei grew emotional while walking alongside her cancer-survivor mother during a fundraiser for victims of the disease.

Kordei recently sat down with news show Entertainment Tonight, days after taking part in the American Cancer Society's Making Strides Against Breast Cancer 5K event in Santa Monica, California and she revealed the experience had a profound effect on her.

The star attended the fundraiser with her mom, Andrea Hamilton, who beat breast cancer 16 years ago.

"The event was incredible. It was one of the best experiences and most memorable that I've had," she said. "It was honestly so surreal, exhilarating, exciting, emotional - just a range of different emotions and feelings, because it's a cause so dear to my heart and close to me and my family because of our experience."

The 21-year-old was excited to participate in the event with close friends and family and found herself moved by the support from other attendees.

"She's a 16-year survivor and it's really special to be able to walk alongside her and our family and friends who came out," Kordei added. "It took nothing but a call to let them know what we wanted to do, and they were so excited to participate. It was just beautiful to see.

"There were little girls in pink tutus and there was a woman there in her pink afro and men out there supporting as well. We had a lot of fun in our pink that day."
