Early Life & Education
Mabel Painter Lowe was born in May 2009 in Los Angeles, California, to actor Chad Lowe and casting director Kim Painter.

She grew up in a Hollywood-adjacent household. Her father, Chad Lowe, is an Emmy-winning actor best known for his role as Jesse McKenna on Life Goes On (1989–1993), a performance that earned him a Primetime Emmy Award. He has also appeared in Melrose Place, Pretty Little Liars, and 9-1-1: Lone Star. Her mother, Kim Painter, works in Hollywood as a casting director and formerly served as late actress Carrie Fisher’s executive assistant.
Mabel is the eldest of three daughters. Her middle sister, Fiona Hepler Lowe, was born in November 2012 and named after Chad’s late mother, Barbara Lynn Wilson. Her youngest sister, Nixie Barbara Lowe, was born in 2016.
Mabel has attended school in Los Angeles and has made rare red carpet appearances with her family over the years, including at the premiere of Marvel’s Moon Girl and Devil Dinosaur in February 2023. She turned 17 in May 2026.
