Early Life
Corinne Massiah was born on March 13, 2003, in Los Angeles, California. She was born one minute after her fraternal twin sister, Halle Massiah, making her the younger of the two by the slimmest possible margin. Growing up as a twin in Los Angeles, Corinne’s parents made a practical and inspired decision: recognizing that the girls had enormous energy and a natural competitiveness with each other, they enrolled both sisters in acting classes as a constructive outlet. What they hoped would channel the twins’ sibling energy into something productive turned out to be the beginning of Corinne’s professional career.
Corinne fell in love with performing immediately. Memorizing lines came naturally to her; inhabiting characters felt instinctive; performing in front of audiences gave her joy. She recognized her desire to be an entertainer at around age 8, the same year she booked her very first professional acting role. Alongside her passion for acting, she developed a love for volleyball beginning at age six, a sport she has continued to play throughout her adolescence and college years. Her cousin is fellow actor Euseph Messiah, suggesting that performance runs in the family.
Education
Corinne Massiah attended high school in Los Angeles, though she has noted that her non-traditional professional schedule made traditional schooling challenging, at points, she was unable to attend middle school in the conventional sense because of her work commitments.
She later enrolled at the University of California, Los Angeles (UCLA), where she majored in Sociology, and graduated in 2025, completing her degree while maintaining her active acting career as a series regular on 9-1-1.
Her academic achievement alongside a demanding professional workload reflects real dedication and organizational skill.
Career
Early Commercials and Television Debut (2012–2016)
Corinne made her television debut in 2012 on the CBS crime drama CSI: NY, booking the role on her very first professional audition at age 8. She followed this with a guest appearance on NCIS. During this period, she also appeared in national television commercials for American Girl Doll, Progressive, and AT&T, building professional experience and income while attending school. A formative early opportunity came when she landed a series regular role in the Kevin Hart sitcom pilot Keeping It Together for ABC (also starring Romany Malco), which was not ultimately picked up to series, but proved invaluable in developing her skills and professional confidence.
She landed a significant role in the action blockbuster G.I. Joe: Retaliation (2013, directed by Jon Chu), playing the daughter of Dwayne Johnson’s character. In a memorable production detail, her fraternal twin sister Halle appeared alongside her in the same production in a scene requiring her character to appear as a clone, one of the more charming behind-the-scenes stories in Corinne’s career.
Breakthrough: Mistresses and Pitch (2013–2017)
Corinne’s sustained television breakthrough came with a major recurring role as Lucy on the ABC drama series Mistresses, in which she appeared across all four seasons of the show. This multi-year commitment gave her extensive professional development at a young age.

9-1-1 (2018–Present)

The show, which premiered on Fox in 2018 and moved to ABC after Season 6, stars Angela Bassett, Peter Krause, and an ensemble of acclaimed performers. Corinne plays May Grant, the daughter of Athena (Angela Bassett), who begins the series as a troubled teenager and develops over subsequent seasons into a 9-1-1 dispatch operator, a role that places her in the high-stakes environment of emergency response coordination. Corinne has appeared in over 70 episodes of 9-1-1, making it the most substantial commitment of her career to date.
