The 23-year-old recipient of an £4,800 NHS-funded breast enlargement is expecting her third son in two months.
Revealing she had several glasses of wine and smoked a whole packet of cigarettes that fateful night, Cunningham is now in the grip of a 20-a-day habit, but hopes to receive NHS help to kick it.
She said: “I knew it could harm my child but it didn’t stop me. Deep down I know I wouldn’t be smoking or drinking if I knew I was having a girl.”
Cunningham, who is currently claiming £6,000 a year in tax-payer funded taxi rides because public transport gives her panic attacks, then appeared to compare carrying a son to a having a run-of-the-mill vehicle, as opposed to the “luxury car” experience of expecting a girl.
“If you’ve already got a couple of Fords and you’re told your next car is going to be an Audi, your excitement goes through the roof.
“You make promises to yourself that you won’t smoke inside the car or let people eat takeaway food in it. But if it was another Ford those things wouldn’t be a problem.
“I know some people will find it disgusting that I started drinking and smoking again simply because I’m having another son, but I’m being honest,” she said.
Earlier this year Cunningham announced her intention to have an abortion to increase her chances of appearing on Celebrity Big Brother, but later changed her mind.
And on Sunday she revealed she was mulling two book deals and expects to have a tell-all volume on the shelves by the end of the year.
I have been offered two book deals, I haven't signed either yet but I will next week - both are very appealing.— Josie Cunningham (@JosieCOnline) June 29, 2014
She tweeted: “I understand why people are judging me in the way they are, all I ask is that before making your conclusive opinion on me, wait for my book to come out at the end of the year.”
Online NHS literature states: “Every cigarette you smoke contains over 4,000 chemicals, so smoking when you are pregnant harms your unborn baby.
“Cigarettes can restrict the essential oxygen supply to your baby, so their heart has to beat harder every time you smoke.”
It states children whose parents smoke are more likely to suffer from asthma and other more serious illnesses that may need hospital treatment.
It adds: “The sooner you stop smoking, the better. But even if you stop in the last few weeks of your pregnancy, this will benefit you and your baby.”
It also cautions that drinking more than six units a day can cause a serious condition called foetal alcohol syndrome.
The wannabe glamour model appears to have been courting the public's wrath since her breast enlargement last year, having subsequently gleefully revealed she's received £1,500 of Botox injections to treat excessive sweating and £2,500 of dental treatment – also funded by NHS.
