Alicia Clark was born in Los Angeles, California to Steven and Madison Clark and she is the younger sister to Nicholas "Nick" Clark by a two-year gap. Alicia and her brother were raised in the neighborhood of El Sereno

When Alicia and Nick were younger, they both attended camping. Alicia was about to perform at the talent show singing "This land is your land". However, when she got up on the stage, she froze and everyone stared at her, marking it as one of her most embarrassing moments. Alicia said that Nick could feel the embarrassment from the audience, but then he got up on stage to help Alicia. Except, when he got up there, he forgot the words. The only thing he could remember was "This is your land" and sung it at least 20 times. When he finished, everyone cheered for him.

Another childhood experience was when she her family went out to a cabin. A bird got injured and the two were determined to make sure it becomes healthy again. They nursed the injured bird and named it Amina. Alicia and Nick were very close when they were younger until Nick started using drugs. It was mentioned that there was always a chance that one of them would come home with a broken arm or some kind of injury

While growing up, Alicia and Nick were often put in the care of Susan Tran and her husband, Patrick - their next-door neighbors, while Madison and Steven were working late or out of town. Alicia especially grew close to Susan, referring to her as "Aunt Susie." When Alicia was around 14, her father was killed in an accident and sometime later her mother started dating Travis Manawa, a high school English teacher and fellow coworker of Madison's at Paul R. Williams High School. While at Paul R. Williams High School, Alicia began dating Matt Sale at some point and would go on to be accepted into UC Berkeley.
