Latimore was born in Milwaukee, Wisconsin the son of Latitia Taylor and Jacob Latimore Sr. When he was five years old he watched the movie The Temptations – an ode to the popular Motown group – and fell in love with music. He spent weeks watching the movie over and over, trying to memorize the songs and learn all the dance moves. Jacob's father and uncles were also musically talented and encouraged his interest. When he was nine years old he decided to take music more seriously and produced his first song, "Best Friend". DJs across Milwaukee took to the song, and “Best Friend” received airtime. At the same time, Latimore was performing at events and festivals across the state, trying to make a name for himself.
