Masterson was born in New York City, to Carol Masterson and Joe Reaiche, a Lebanese-Australian former professional rugby league footballer with the Sydney Roosters and the South Sydney Rabbitohs. She is the younger sister to her brother, Jordan Masterson, and two half-brothers, Danny Masterson and Christopher Masterson. After some time on Long Island, the family later relocated to Los Angeles. She grew up around and was influenced by her older brothers who both starred in popular television shows in the late 1990s and early 2000s. Masterson's passion for acting came from spending a lot of time on set with her brothers and seeing the filming process.
Masterson has portrayed Tara Chambler on the AMC TV series The Walking Dead, beginning in the show's fourth season. Masterson was promoted to a series regular for the fifth season and was added to the main credits in the seventh season. Additionally, she had a recurring role in the fourth season of the ABC series Mistresses.
On November 4, 2015, Masterson and ex-boyfriend Brick Stowell had a daughter, Marlowe.
