Jonna Mannion is one of the cast members of The Real World: Cancun. The 20-year-old from Tempe, AZ has had a rough life ever since—she was put in foster care at age 4, living with a very religious family, and was eventually adopted by her caseworker, who ended up kicking her out of the house. An aspiring hairdresser, she wants to stay faithful to her boyfriend back home while in Cancun, but her promiscuous past always catches up with her—luckily she has her friend (and fellow contestant) Derek in tow.
