Heartbroken Sarah McManus is carrying the couple's second child while keeping a vigil by the former Celtic favourite's bedside.
Hartson, 34, found out Sarah was pregnant again only weeks before his bombshell diagnosis with testicular cancer.
LEAVE YOUR MESSAGES OF SUPPORT BELOW
The couple already have a year-old daughter Lena and ex-Arsenal and West Ham star Hartson told pals he was "thrilled" at the prospect of another child arriving in December.
But last night he was fighting for life after the cancer spread to his brain and lungs.
The 6ft 2in former Wales international had emergency brain surgery this week to relieve tumour pressure. He remains "critical but stable" in hospital in his home city of Swansea amid fears he may have only days to live.
A family friend said: "Everyone is praying for a miracle. John has so much to look forward to with the new baby and it's heartbreaking to think it may be born without knowing its father.
"Sarah just doesn't want to leave John's bedside but she comes home to eat and put Lena to bed. It is a horrible time for her and the family." Sarah, a 37-year-old art teacher, has been making daily trips to his bedside from their home in nearby Neath, West Glamorgan.
Her mother has travelled down from Scotland to help look after Lena but the family are concerned about the stress Sarah is under during the early part of her pregnancy.
The friend added: "It had all been going so well for them. They are a lovely couple together and they were delighted when Lena came along last year.
"But now John is fighting for his life in hospital and Sarah is worried sick about him."
Striker Hartson was earning £40,000 a week at Celtic when he began seeing Sarah while still with wife Lowri, 32, the mother of his two other children, Rebecca, 10, and Joni, six.
He had been with Lowri for more than 12 years when she found out about the affair. After an expensive high-profile divorce Lowri now lives on a gated mansion near Swansea.
Hartson and Sarah moved into a four-bed detached house in Neath last year to start a new life together after he retired from football.
He had begun building a career as a TV pundit and had also been touted as a potential club manager.
But earlier this year he discovered a lump in his testicles and ignored it, thinking it would go away.
Nine days ago he went to Swansea's Singleton Hospital suffering from severe headaches. He was kept in for tests and last Sunday was given the shattering news that he had cancer. He was later transferred to the city's Morriston Hospital for emergency neuro surgery.
The local health authority has been releasing twice-daily bulletins about his condition and doctors say that if he does pull through he will face months of chemotherapy and radiotherapy.
Football internet sites have been swamped with messages of support for Hartson, who began his 16-year career as a teenager with Luton Town, had spells at West Brom, Wimbledon and Coventry City and won 51 Welsh caps.
His sister Hayley, 25, told a Celtic fans' website: "I would like to thank you all for your support through this devastating time for John and the family."
Hartson's family said in a statement: "We have been overwhelmed by the support and goodwill from thousands of fans, players, clubs and sporting figures. We have drawn strength from this."
Tour de France cycling champion Lance Armstrong, who beat the same cancer after it riddled his body, also sent words of encouragement
Cancer specialist Dr Gianfilippo Bertelli said: "We are aiming for a positive outcome. We realise Mr Hartson is a much-loved figure."
A Celtic spokesman said: "John has served the club, and the game of football in general, with distinction over many years. Everyone fully supports him and his family."
Just a few weeks ago Hartson played in a memorial match for Celtic legend Tommy Burns, who died of skin cancer at 51 in 2008.

Its not fair that a man who brought so many people so much joy and excitement can be dealt such a bad hand in life, I think i speak for most football fans out there when i say " we may not have supported you on the field but we are now all supporting you in your time of need" fight hard John you have have a beautiful family and we would all love to see you grow old together.

By Vince K.. Posted July 19 2009 at 2:48 PM.
John,
4 years ago, my wife had treatment for small cell lung cancer. This is a cancer which, according to statistics at the time, less than 3% make it past 5 years. She is almost there.
Her treatment lasted 9 months. It was anything but easy however, when it was over, she reclaimed her life and carried on as normal.
I never quite understood the term "fighting" the disease. Watching her come through the treatment, she remained positive, surprisingly, laughed quite a lot with the nurses and doctors. The doctor in charge was magnificant, brutally honest but great charm which kept her smiling. I think this is what kept her going.
The whole of football is wishing you well.
Regards
Ray, Fulham supporter, now living in USA.
By Ray Jarvis.. Posted July 19 2009 at 2:24 PM.
God bless you, John and your family. May you take on this battle with all guns a'blazing. Lance Armstrong did it.......you can too.
Take care, big man....the whole country is behind you.
By Sian and Walter, Neath.. Posted July 19 2009 at 2:23 PM.
Wishing John all the best of lucky and hope you can overcome this. I will never forget my first match at Upton Park against Huddersfield in the league cup and John scored his very first hatrick for the Hammers, great memoires.
Stay strong and I hope for you and your family you have many years ahead of you.
