"My mom showed up unannounced to my house when she knows I have no interest in seeing or talking with her," Montag told People magazine. "She tore my heart out on national television. She is just trying to create drama in my life."
Los Angeles police confirmed that Egelhoff came to Montag's house on Thursday and was turned away, according to the report.
"Officers arrived on the scene and advised the mother that since her daughter is an adult, she doesn't have to speak to [the mom] if she doesn't want to," Los Angeles Police Department Sgt. Leffew told the magazine. "The mother said 'fine, no problem' and left. There were no citations or arrests."
Montag asserts that she's done with her mother.
"I made it very clear that I want nothing to do with her in my life right now," she said. "I'm sick to my stomach she would even do something like this. She needs to stay away from me. I'm planning on getting a restraining order against her."
Earlier on this season of "The Hills," Montag returned to her mother's home in Colorado to show off her new look after undergoing 10 plastic surgery procedures in one day. Her mother's less-than-thrilled reaction drove the reality star to tears and prompted her husband and "Hills" co-star, Spencer Pratt, to declare that Egelhoff "decided to rape my wife emotionally."
