A model in court for drug possession was later nabbed with methamphetamine she forgot was in her Chanel handbag, while visiting her bodybuilder boyfriend in a Melbourne prison.

Jonita Ragaisyte, 27, has pleaded guilty to two charges of possessing a drug of dependence, more than two years after police found an "Aladdin's cave" of drugs at the apartment she shared with her then-boyfriend Cemre Volkan.

Volkan was jailed last year for drug trafficking and possession after police found cocaine, GHB, ketamine, LSD, MDMA, steroids and testosterone in the Docklands apartment.

Ragaisyte has since admitted to possessing the GHB-alternative butanediol as well as n-ethylhexedrone, a drug with similar properties to methamphetamine.
