Joi (played by Paula Jai Parker) is Craig's girlfriend (now ex-girlfriend), who always mistakenly thinks that Craig is cheating on her whenever a lady is near Craig, such as Debbie and Felisha. Craig eventually breaks up with Joi in favor of Debbie. Joi only appears in the first film.
Ironically, she is shown in bed with an unnamed man while on the phone with Craig. She is what could be considered a hoochie mama, having a Ghetto-Fabolous personality.
