On Thursday, the Hills star called police after her mother, Darlene Egelhoff, arrived at her Los Angeles home.
“My mom showed up unannounced to my house when she knows I have no interest in seeing or talking with her,” Montag, 23, tells PEOPLE. “She tore my heart out on national television. She is just trying to create drama in my life.”
Montag and her mom have let the drama unfold on camera too. Earlier this season on the Hills, Montag returned home to Colorado to show off her new body after undergoing 10 plastic surgeries in one day. Her mom’s reaction drove the reality star to tears and prompted her husband, Spencer Pratt, to declare on Tuesday’s episode, that Egelhoff “decided to rape my wife emotionally.”
