A MUM shared revenge porn videos after her boyfriend cheated on her while she was in labour with their child — now she has ended up on the sex offender register.

The Sun reports Lorraine Donoghue, 32, has admitted her actions were “nasty” and warned women not to do the same thing.

“I regret what I did, I got into a lot of trouble and although it’s no excuse, I acted in the heat of the moment out of hurt and anger,” she said.

Donoghue was devastated when she found a pair of women’s pants and a sex toy under her boyfriend Willie Crawford’s bed in April.

The UK mum of three — who had only given birth to the couple’s daughter six weeks previously — was then horrified to find graphic pictures and homemade sex videos of her 37-year-old partner with his teenage lover of 18 on his Facebook account.

Furious the dad of four had been cheating on her, Donoghue says she sent around six of the intimate images to friends in private messages on Facebook.

She also sent images to the girl’s mum and boyfriend along with the message: “Here’s your girlfriend.”

Now after escaping a prison sentence, Lorraine has spoken out to warn others — and told how she was hauled in front of the courts for trying to get back at her cheating ex.

“I couldn’t believe he would do this to me. When I realised she knew about me too and was happy to sleep with him behind my back when I was pregnant, it just left me speechless,” she said.

“There were loads of messages between him and her, even discussing what I’d found, and I knew then they had been sleeping together behind my back while I was pregnant for about a year.

“In a moment of madness and utter desperation and anger, I took some screen grabs and mailed them to people I knew.

“I even sent them to Willie and the girl and although I knew it was really nasty, I sent some to her mum and her boyfriend so they could see her and what she was doing.”

In messages, love rat Crawford promised the teen that he was “100 per cent” hers and that he had chosen her over his newborn daughter.

Donoghue claims Crawford and his teenage lover began to taunt her, including sending her a photo of the teen sitting on the couple’s former bed.

Now Donoghue has warned other women not to seek revenge and risk jail time.

“I know it was stupid, but it was done in a moment of utter madness when I was so deeply hurt,” she said.

“I knew he was a womaniser and he had cheated before but when I left he wouldn’t leave me alone and begged me to take him back.

“In the end, he wasn’t worth it. I am a mum and have kids to think about and I shouldn’t have done what I did.

“I just want to move on and put the mess behind me but I want other women to be aware of the real dangers of getting back at any cheating lover.”

At Falkirk Sheriff Court last month, Donoghue pleaded guilty to contravention of the Telecommunications Act by sending indecent or obscene photos by means of a public electronic communications network.

Her pleas of not guilty to two further charges, of causing the other girl’s mum and boyfriend to look at a sexual image by sending them unsolicited messages by social networking, were accepted.

In October, Donoghue had been placed on the sex offenders’ register — usually used for rapists and paedophiles — but last week she was shown mercy.

Sheriff Linda Smith cancelled an interim order which had put Donoghue on the sex crimes register, and ruled that her offence contained “no sexual aggravation”.

Lorraine was placed under supervision for 15 months and ordered to do 120 hours unpaid work for sending the “obscene” images.

Sheriff Smith said: “Clearly your motivation was vengeful, not sexual.”
