Rodriguez was born in Bryan, Texas. Her parents are Diane and Roy Rodriguez, who own a Rodriguez Tire business. She is the older sister of actor Rico Rodriguez. She has two other brothers, Ray and Roy Jr.
Raini Alena Rodriguez was born on July 1, 1993 in Bryan, Texas. Her parents, Diane and Roy Rodriguez, own a business called Rodriguez Tire Service.
As a young girl, Rodriguez enjoyed acting. One day, at an IMTA showcase, Raini was discovered by Susan Osser, a Californian talent agent. After viewing Raini's performance, Osser suggested to Raini's mother if Osser could become Raini's manager and to come to California to give Raini a year for career opportunities. At the time, Raini was eleven years old. Her mother agreed to Osser's proposal. Raini (alongside with Rico, her little brother, who also was signed a talent manager) moved to Los Angeles. Diane accompanied them temporarily while Roy stayed in Bryan to run the tire shop. Their mother even home-schooled them to support their blooming career.
