Stephanie Pratt Estranged From Heidi & Spencer

The Hills’ Stephanie Pratt has found herself estranged from her older brother Spencer and her surgically-enhanced sister-in-law Heidi Montag.

In a new chat with Fancast.com, Stephanie revealed that she hasn’t been in contact with The Pratts for months, and notes that Heidi & Spencer didn’t even bother forging a reconciliation during the holidays.

“I haven’t talked to Heidi or Spencer since September. I feel so dumb not to know what’s going on with my family. But they’ve decided they don’t want me in their life, so I don’t know what’s going on with them.”

Stephanie — who was collared for DUI last fall and later spent several weeks in rehab — isn’t sure what incident set off the estrangement, but the ditzy blonde calls the separation “sad.”

“I’m kind of mourning the loss of him. But that’s his choice. He cut a lot of his friends out. I don’t know what’s going on with him.”
