When thieves aren't targetting the oft-robbed Rich The Kid they're hitting his shady girl Tori Brix.

Brix was one of several victims of a home invasion during a birthday party earlier this week in a Los Angeles rental house.

During the celebration, six armed men in masks entered through a back door and made off with about 100K in cash, jewelry, purses, and phones.

Before the robbery, some of the 15 to 20 people at the celebration had been posting videos of the party on social.

Brix was notoriously roughed up after robbers entered her apartment a couple of summers ago when Rich was staying there and took money and jewelry from the rapper.  We say "notoriously" because her injuries looked like they were applied by a makeup artist and the cops labeled the incident an inside job.

No word on suspects or motives in the latest home invasion.
