Heidi: "Spencer Didn't Change Me"
The Hills star claims she changed herself...
Pratt has previously been accused of brainwashing Heidi with reports suggesting he doesn't let her watch TV or use the computer.
He is also said to have called the police on Montag's mother after a row in which he allegedly verbally attacked her.
In a new episode of the reality TV show, Montag confides in Kristin Cavallari about Spencer stating: "I think he's just had a lot going on with our families and everything that's happened."
When Partridge replies, "It sounds like you're in denial", Montag responded: "All guys are a little bit controlling. You don't know me. Spencer didn't change me. I changed myself."
Despite the reality TV star denying any problems with Spencer, Heidi's father, Bill Montag has also claimed he is worried about his daughter follow the reports about her lifestyle with Pratt.
Bill told Star magazine: "If I don't hear from them soon, good or bad, I will take my family and get his family and go there and talk to them. They can call the police on me too. I want to make sure both of them are OK."
