Probation Department spokeswoman Kerri Webb says Alexis Neiers was taken into custody Wednesday morning after officers went to her home for a compliance check and found the drugs and paraphernalia.
Webb says officers also found Neiers with a Florida driver's license that showed a false age.
The aspiring model, who was on the E! Entertainment Television show "Pretty Wild," is being held without bail.
The 19-year-old spent 30 days in jail this year after pleading no contest to burglarizing Bloom's house as part of a group accused of several celebrities' home break-ins.
A call to her attorney, Jeffrey K. Rubenstein, was not immediately returned.
