She cheated on the guy she was living with.
The person she cheated with is a former A list television actor from two simultaneous network hits who still makes a very good living on television, just not as an actor.
She got pregnant and had a miscarriage but didn’t tell the actor for three months and kept milking money from him to help pay for her future life with their child.
Holly Madison, Barry Williams
They did “40 Smokin’ On-Set Hookups” together in 2007
