The Foundations star took to Instagram on Saturday (19Mar16) to document the horrifying encounter.

"2 days ago I got groped in my own house by a man I don't know," the 28-year-old wrote. "I was alone & cornered in a bathroom & extremely threatened."

She stopped short of going into further detail about the incident, but urged fellow victims to speak out if they find themselves in similar situations, suggesting she has reported the intruder to police.

Nash continued, "I'm sharing this information with you because women are encouraged to keep quiet, not take up space & hide when they get violated.

"We are scared to come forward because we don't want to cause trouble or a scene. We don't want to talk about heavy s**t & make ppl (people) feel uncomfortable. Women & girls are also mostly told they were asking for it & accused of making it up. So sometimes we think twice about coming forward, or we don't at all. I'm tired of feeling that way.

"Talking about these issues can a) help to prevent them in the future & b) make us feel stronger, more supported & safer."

Nash accompanied the Instagram post with a 'selfie', in which she is featured wearing sunglasses, with a cigarette hanging from her mouth.

"we don't have to look like a victim to be one," she added. "I actually happen to be a bada** b**ch from hell, this s**t can happen to anyone."
