Heidi Montag’s father, Bill Montag, was arrested Thursday night in Colorado for alleged sexual abuse and incest with a 13-year-old girl. A complaint claims Montag abused the girl, who is now 17, at least 50 times between 1993 and 1998. The complaint describes the last incident as a night when Montag crawled into bed with the girl and attempted to have sex with her, but she rebuffed his advances. TMZ cites sources “who are very close to Heidi and [her husband] Spencer” who say the girl has stalked them at public appearances. The couple apparently believe Montag will be exonerated.
