He was mainly raised by his grandmother.
Born Jahseh Dwayne Onfroy on January 23, 1998 in Plantation, Florida, XXXTentacion was separated from his mother at an early age. His mom, who was pregnant with him as a teen, had financial issues, so he often lived with other people. By the time he was 12, he began living with his grandmother.
"My grandma really feels like my mom," he said in a Miami New Times article. "My mom almost feels like more of a sister."
He gained notoriety on SoundCloud.
The musician gravitated towards music after his aunt persuaded him to join a choir, he once said in a No Jumper interview. Although he was kicked out for fighting, he continued to dabble in music, exploring nu-metal, hard rock and rap.
He released his first track “News/Flock” on SoundCloud in 2013. As he continued to upload new music, his fan base grew. He garnered thousands of streams, and by 2018, he had more than 2 million followers.
