Heidi Pratt -- who called the cops on her mother Darlene Egelhoff Thursday -- isn't the only Hills star clashing with her family.
Her husband Spencer also has distanced himself from his family, reports the new Us Weekly (on newsstands now).
He is estranged from younger sister Stephanie and doesn't speak to his folks because "he felt his parents would talk to him only about Stephanie and that they charged him with taking care of her," an insider tells Us Weekly. "He thinks she's a loser and doesn't want anything to do with her."
Apparently, his parents have had it with him as well.
"They noticed him changing two years ago and stayed by his side. But now it's too much," a source tells Us Weekly. "They even took the pictures of him out of their home."
Us Weekly reports Spencer, 26, and Heidi, 23, have become virtual shut-ins at their $7,000-a-month rented L.A house, which is filled with framed covers of magazines on which they've appeared.
"No one ever visits," a local tells Us, and the couple rarely leave. "Heidi sits and stares in the mirror, while Spencer plots and schemes on his projects all day," adds a Pratt source. "He sits on the Internet, watches TV and tries to get press. That is all he does. It's totally sick."
