"I told my mom a while ago I need space from her. And she just showed up at our door unannounced and tried to get in. She was yelling about how I was being held against my will which couldn't be farther from the truth," Montag tells People.

The West LA police department have confirmed that Montag's mom went to the home to speak with her daughter. Sgt. Gary Leffew tells the mag, "Officers arrived on the scene and advised the mother that since her daughter's an adult, she doesn't have to speak to [the mom] if she doesn't want to. The mother said 'fine, no problem' and left. There were no citations or arrests."

Various online reports claim that Montag is now seeking a restraining order against Egelhoff.

Calls to Heidi's rep have not been returned.
