Gelula was born on May 7, 1994 in Philadelphia, Pennsylvania, to Karen, an attorney, and Jonathan Gelula, who owns a private label wine Business. She was raised in Reform Judaism. She attended Lower Merion High School and recalls having a difficult time in high school, having been "very lonely, but very comfortable being alone," and showed up to school so infrequently that she was forced to either repeat her senior year or drop out. She ended up dropping out and moving to Los Angeles by herself at the age of seventeen.
