Jonathan "Jo" Rivera is the father of Isaac Rivera and the ex-boyfriend of Kailyn Lowry. He was 18 years old when Isaac was born.
After his messy break-up with Kailyn, Jo began dating Vee Torres, whom he married in 2011. In 2015, they welcomed their daughter, Velisse "Vivi" Rivera. The family of three relocated to Delaware so that they could remain active in Isaac's life following Kailyn's move after marrying Javi Marroquin.
