Identity Revealed: Heidi Montag’s Stepsister Comes Forward As Father’s Abuse Victim

In recent years, The Hills: New Beginnings star Heidi Montag Pratt has been forced to face shocking allegations her own father sexually abused a minor female.

But the pain is even more devastating for the 32-year-old reality star’s stepsister, Carissa Berlet — who is courageously speaking out for the first time in an exclusive interview with RadarOnline.com about the horrific abuse she claims she endured at the hands of her stepfather, Heidi’s father William Montag.

“It got to the point where I couldn’t hide his secret anymore,” said Carissa, whose name had been redacted from the Colorado court case. Perhaps identity monitoring was needed. But when contacted by Radar about the case, she decided to come forward for the very first time.

Colorado-based mom Carissa, 38, said the #MeToo movement has been encouraging for her.
