SERIAL killer Joanna Dennehy plans to marry her fiancee who told her she couldn't attack anyone while they were together, it's reported.
The triple murderer reportedly wants to tie the knot with street robber Hayley Palmer, who has been released from prison.
Dennehy proposed to street robber Palmer after they fell in love behind bars at the privately-run HMP Bronzefield women’s prison.
Pals claim Palmer, who served a 16-year sentence, is taking legal advice on marrying 38-year-old Dennehy, The Mirror reports.
Street robber Palmer is said to have changed her name to Dennehy.
A source told The Mirror: “It’s a very strange relationship. It’s very weird to say but they seem good for each other.
“Hayley speaks about Joanna like she’s her high school sweetheart. They talk every single day and fully intend to get married.
"Hayley joked that they would not be allowed to cut their wedding cake because there’s no way that they’d let Joanna have a knife.
“They want to be married by the end of the year. They’re both committed to it.
"Now Hayley’s out of prison, she’s petitioning for permission to get married as soon as they can.”
Dennehy is one of only two female prisoners serving a whole life sentence in the UK.
The other is Rose West.
She stabbed three men to death over a 10-day period in March 2013, before knifing two others, both of whom survived.
The source added: “According to Hayley, the only reason Joanna hasn’t killed anyone in prison so far is because she wouldn’t let her.
"They have an agreement that Joanna couldn’t attack anybody else while she is in a relationship with Hayley.

"She hasn’t got in trouble in prison while dating Hayley and Hayley is more stable than ever.”
The couple once made a failed suicide pact.
Palmer was released from jail last month on and is now staying at a London bail hostel.
She has reportedly met with lawyers to discuss marrying Dennehy in HMP Low Newton and wants her family to get to know her serial killer partner.
The Mirror's source added: “Hayley is looking to get human rights people involved as Joanna isn’t allowed visitation.
"Joanna is the more girly one so Hayley would not wear a dress for the wedding, she’d probably wear a suit.”
Branded “pure evil” by criminology experts, Dennehy, of Peterborough, Cambs, said she committed the murders because it was “moreish and fun”.
Her victims’ bodies were found in ditches in Cambridgeshire.
Dennehy's first victim, Lukasz Slaboszewski, was her housemate.
She convinced him to meet up, implying that they would have sex.
Instead she stabbed him in the heart and dumped his body.
The following week 56-year-old Falklands veteran John Chapman was knifed to death by Dennehy.
Later that day she murdered her landlord and lover Kevin Lee, 48.
His body — dressed in a black sequin dress — was found the following day with stab wounds in the neck and chest.
It was reported that Dennehy had wanted to kill nine men in total, to be like killers Bonnie and Clyde.

She was caught two days after going on the run when police launched a triple murder probe.
At the Old Bailey, judge Mr Justice Spencer told her: "Although you pleaded guilty, you’ve made it quite clear you have no remorse.”
“You are a cruel, calculating, selfish and manipulative serial killer.”
