YK Osiris has been arrested for allegedly beating his girlfriend up at his own birthday party.

He was arrested on Monday in Atlanta on a felony charge of aggravated assault by strangulation, according to TMZ.

The police report says that YK Osiris’ girlfriend told cops back in September she got into a fight with him at his birthday bash and it ended with him choking her and allegedly biting her in the face.

His girl added that she confronted Osiris after seeing a pic in his phone of another woman wearing nothing but a towel.
