Ben Affleck’s Ex-Nanny Files Restraining Order Against ‘Erratic’ Acquaintance

Ben Affleck‘s ex-nanny has filed a restraining order against an alleged admirer she says took things too far … claiming he’s continued to try and contact her even though she asked him to stop — and she even suspects he gave her cocaine instead of Adderall.

Christine Ouzounian — Affleck’s nanny while he was still married to Jennifer Garner — filed legal docs asking for a temporary restraining order against Matthew Humiston … claiming he acted erratically at a work conference last month, grabbing her wrist so hard that it was sore for days after.

Ouzounian says she blocked Humiston … demanding Matthew not reach out to her again. She says this alleged incident was just the latest in a series of problematic interactions she had with him dating back to December.

Christine says she’s worried Matthew could ruin her professional reputation … and, she’s included what she says are numerous communication attempts by Matthew since she cut off contact with him — alleging he’s called, texted and emailed her repeatedly.

You may remember Ouzounian … who reportedly told her friends she had an affair with Affleck while he was married to Garner — though he’s always denied the claims.
