Roberts was born in Rhinebeck, New York, to Kelly Cunningham and actor Eric Roberts. Her parents separated when she was a baby. Through her father’s marriage, she is the stepdaughter of Eliza Roberts and step-granddaughter of David Rayfiel and Lila Garrett. Through her mother’s marriage, she is the stepdaughter of musician Kelly Nickels. She has a maternal half-sister, Grace. Her paternal grandmother was acting coach Betty Lou Bredemus (1934–2015), and her aunts are actresses Julia Roberts and Lisa Roberts Gillan. During her childhood, Roberts spent time on the sets of her aunt Julia’s films. These experiences sparked a desire to follow her father and aunts into the film industry.
