Murderer Trudi Lenon is in hospital after she was reportedly attacked inside prison by a fellow inmate.
Lenon, who is in custody at Bandyup Women's Prison awaiting sentencing for the murder of Aaron Pajich, was attacked by a prisoner on New Year's Day.
It is understood she sustained serious burns during the incident, and was taken to Fiona Stanley Hospital for treatment.
The Department of Corrections confirmed Lenon was the prisoner injured during the assault, and the incident has now been passed onto WA Police for investigation.
A Fiona Stanley Hospital spokeswoman told WAtoday Lenon was still recovering at the health campus on Tuesday, and was in a stable condition.
The Perth mother-of-three is due to be sentenced for her part in the murder of 17-year-old Aaron later this year.
Lenon was found guilty of his murder in December following a five week trial in the Supreme Court of Western Australia.
The court heard a "vulnerable" Mr Pajich, who had Asperger's syndrome, was targeted and lured to the house by Lenon, who knew the teenager through her 14-year-old son.
She invited Mr Pajich to meet her and her 'landlord' Jemma Lilley at Rockingham shopping centre around 9am on June 13.

Mr Pajich's body was discovered around a week later buried in the pair's backyard garotted with multiple stab wounds to his chest and neck.
Both women denied murdering Mr Pajich and blamed each other.
Lilley claimed she was unaware Mr Pajich had been killed and that Lenon must have murdered him and concealed the crime while she was taking a three-hour nap in the next room.
Lenon however admitted witnessing Lilley stab Mr Pajich to death, claiming she helped conceal the crime out of fear.
Both originally lied to police and told detectives they had not seen Mr Pajich the day he went missing but later admitted he had visited their home.
The women will be sentenced for the crime on February 23.
