"He’s been unfaithful more than ten times. Things went wrong quite early on. Two weeks before we got married he was cheating.photos
"At that time I was eight months pregnant with our first son, Leon, and I felt I had no choice but to get on with it. It was a mistake but I was naive and just hoped it was a one-off.
"I was desperate to have a stable family life and give the kids a home with a mum and a dad – something I’d never had but always craved."
Mrs Prudham also revealed on Facebook the sex of her baby, saying: "I'm having a GIRL!!" which was greeted with congratulations.
She then added her eighth girl will have a double-barrelled name, saying: "I want a double barrel name, first name needs to begin with L like my Lexi-Rose, Lacey-May and Lainey-girl."
She later said that due to the amount of children she already has, she has "run out of ideas" for names.
Just hours after posting the news, she shared a scan of the baby with the caption "my princess".
Finally, she decided against the child's name beginning with "L" and revealed she will call the baby "Tillie-Grace".
The mother, from Gravesend, Kent, who had twins in August, hit the headlines at the beginning of the year after posting a scan of her 12th child. Before quickly saying it was a joke - yet it wasn't.
Mrs Prudham has previously claimed it is "easy" to claim tens of thousands of pounds in benefits.
The Prudham's earn more than the Government's £26,000-a-year benefits cap because working as carers allows them to claim tax credits.
Mrs Prudham, who had her first son when she was 17 and living in a homeless hostel, says she is proud of having 11 children. She has insisted she is not a "lazy layabout" and says her husband also works.
She told Closer magazine: "It's the Government's fault I've got so many kids. It's easy to claim benefits.
"I've always wanted a big family and being a mum is the best feeling in the world. We didn't rush into the decision to have more children lightly but we knew we'd be able to afford it."
Mrs Prudham found out she was pregnant in October, just weeks after she had her twin daughters.
The couple, who lived in a five-bedroom semi-detached council home both work 20 hours a week as carers for the elderly.
Mrs Prudham had her first child, George, 14 when she was just 17, then had Jack, 13, Caitlin, nine, Maisie, eight, Millie, six and Madison, six, all from previous relationships.
With Mr Prudham, she had Leon, four, Lenny, three, Lainey, 23 months and Lacey-May and Lexi-Rose who were born in September.
When asked about her claims, he told the Sunday People she was a "liar", then admitted he had cheated while the couple were "on a break" from each other.
He said: "She’s been with people behind my back. I’m not allowed to see the kids, I haven’t a clue why. It’s over. We split up because she is pregnant with someone else’s baby."
This is really a baby making machine.
