We just spoke with Heidi, who tells us, "My mom [Darlene Egelhoff] just showed up to the house unannounced ... and after what she did to me on national TV, I have no desire to see her."
Heidi's referring to a recent episode of "The Hills" in which Darlene told Heidi she did not approve of her plastic surgery. On this week's episode, Spencer claimed Darlene "tried to rape [Heidi] emotionally."
Heidi tells us she immediately notified her personal security team when her mom showed up "pounding on the door."
Heidi claims Darlene is currently speaking with police.
Montag continues, "Her showing up is completely out of line and psychotic. I’m getting a restraining order against her."
So far, no arrests have been made.
UPDATE: Law enforcement sources tell TMZ Heidi's mom has finally left the property.
