The 'Super Bass' singer is alleged to have confronted a worker at her Hollywood home yesterday (October 28) after mistaking her for someone she fired earlier this month for asking to sign a stolen picture.
According to TMZ, Minaj took exception to the maid's accusations that she was being "treated like an animal", apparently saying: "I'll show you how to treat someone like an animal... get the f**k out of my house!"
Minaj's boyfriend is said to have made physical contact with the maid during the fight, at which point her boss called police and filed a battery report.
The helper also intended to make a citizen's arrest, but decided against it when authorities arrived to talk to Minaj.
Minaj was this week confirmed to make an appearance on Madonna's new single 'Give Me All Your Love' alongside MIA.
