When Martell first appeared on screen, he used his father Wes Lieberher's last name. However, he legally changed it to his mother Angela Martell's maiden name in 2019. Martell opened up about his decision to change his last name in a 2020 interview with GoldDerby, explaining, "That is my mom's last name, and I wanted to honor her because she is here with me every day that she's on set with me, and she makes me the person I am. I owe everything to her, and she has raised me the last 17 years."
Martell is incredibly close to his mother and often shares his gratitude for her on his social media. "Happy Mother's Day to the most beautiful, caring, strong person I know. She makes me a better human everyday. I won't ever be able to repay her for the sacrifices she's made for me. Love you so so much, mom," he captioned a series of sweet snaps with his mom on Mother's Day in 2019.
