According to TMZ, Nicki Minaj got into an altercation with one of her maids at her house in Hollywood.
Here's supposedly what went down: Nicki fired one of her maids two weeks ago for taking a picture of her out of the garbage and then asking her to sign it. The maid however, did not seem to get the hint and came back to Nicki's house yesterday (October 27th). Nicki was pissed off at her, yet again, and asked her to leave. It seems that the maid was remaining persistent and refusing to leave, so a fight broke out between them. It is unclear though whether this was a case of mistaken identity-- different sources have conflicting stories, one saying that this was the actual maid that Nicki fired two weeks ago and another source saying that it was different maid.
Nonetheless, Nicki's boyfriend, Safaree Samuels, ended up getting involved and started using physical force on the maid. The maid's boss ended up calling the police on him and filing a battery report. When the cops arrived the maid asked for Samuels to be arrested, but in the end she changed her mind so noone was taken into custody.
