A FORMER reality TV star from Beauty and the Geek has been arrested and charged with murder after her partner’s body was found in their house.

Emergency services were called to the home in Port Lincoln, South Australia, to reports of a fire.

When they investigated, they found a man’s body in a grisly scene.

The unnamed 34-year-old was arrested at the scene and later charged with murder.

She was once a contestant on reality show Beauty and the Geek, reports The Courier Mail.

The social experiment programme brings together attractive women with nerdy men in a mansion.

The victim and the suspect had been in a relationship together, South Australia Police confirmed.

The woman refused bail and remains in custody.

Major crime investigators and forensic officers were flown into Port Lincoln to assist local authorities with the investigation.

Neighbours were shocked by the news.

One told Perth Now the woman is “really nice, very pleasant, polite.”

Ian Parrott, of South Australia Police, said: “I can reassure members of the community that this is not a random incident.

“We understand that the female who has been arrested and the deceased male both lived at this address.”

It is understood the couple had recently moved in together.

He continued: “It is still very early stages of this investigation and it’s likely that the Major Crime investigators and the forensic response members will be there most of today.”

Parrot said the cause of death was yet to be determined and that further details could not yet be released as the victim’s family hadn’t been notified.

The woman has been detained under the Mental Health Act and did not seek bail.

She is expected to return to court in December.

A suppression order is in place preventing the publication of any information that could identify the woman, the victim, or details surrounding the man’s death.

That order is due for review by the court next week.
