A Halloween party at Jamie Foxx's Thousand Oaks mansion ended in chaos Saturday night after a guest was reportedly stabbed in the neck, according to Complex and multiple other outlets citing TMZ. The party was hosted by Foxx's daughter, Anelise, at the actor's home.

Paramedics treated the victim's wound at the scene; reports describe it as a superficial stab wound, and there's no indication he was transported to a hospital. A suspect was taken into custody on suspicion of assault with a deadly weapon, though authorities haven't released the person's name, and it remains unclear exactly what was used in the attack.

NO REAL OR FAKE WEAPONS.

That was the rule posted at the party's entrance, according to Yahoo Entertainment's report on the incident — making the stabbing all the more jarring for guests who'd been told the event was meant to be weapon-free. It's not clear whether Foxx himself was home at the time, and he has not publicly addressed what happened.

The incident adds an unwelcome footnote to what was otherwise a high-profile Halloween weekend on the party circuit, with CBR and other outlets noting the investigation remains active. No further details on the suspect's identity or motive have been released, and it's unclear whether charges beyond the initial arrest will follow.
