On AOL's upcoming My Hero, the Teen Wolf star is honoring his mom, who has been battling cancer for four years.
"My mom is a hero to me. I don't think I could pull off her bravery," Tyler says in a sneak peek clip. "Since I found out that she was diagnosed with breast cancer, there were a lot of things I didn't want to accept and come to terms with, and it was a really hard situation for me."
"She kept our family together while being in chemo and dying," he continued. "She's sat us down about four times now and told us that she's had different types of cancer, so it gets scarier and scarier every time. She's just been this rock. She knows how much we love her; she deserves to hear it."
Nick Cannon, Jane the Virgin star Gina Rodriguez and Julianne Hough are also featured on episodes of the show, which premieres Friday at midnight.
