The actress and mother-of-two, from Ashton in Makerfield near Wigan, confirmed she is back together with former Hollyoaks star Jamie Lomas as she accepted the award.
Marsh, 33, plays barmaid Michelle Connor in the ITV1 soap and is mum to David, 14, and Emily, 11.
She and Lomas had to cope with the death of their premature baby boy earlier this year. Archie Jay Lomas was born 18 weeks early in February, and died moments after birth.
Marsh said: "Yes we are back together. Jamie has got a son of his own and he is a very good father but he can't win Celebrity Mum of the Year!
"It is a real honour to get this award. It is nice to know I have got a lot of support out there, it has been a really difficult year.
"I have been a single parent in the past and I have had struggles so hopefully people still think I have done the best by my children."
The former Hear'Say star accepted the Bounty Celebrity Mum of the Year 2009 Award, voted for by the public, at the Lowry Hotel in Manchester.
Marsh is divorced from former EastEnders star Jack Ryder and split up with Lomas last month, only for them to reconcile.
Her two children are from a previous relationship with Dave Cunliffe.

speaking as someone who used to work in 'showbiz', i can tell you actors don't know the meaning of the word 'work'!

How do you work full time and have your kids full time ?(unless you take them to work with you)
How do you you know she doesnt do her own ironing an cleaning? Why are you so down on her, yes she has won celebrity mum of the year, maybe if we had a 'non celebrity' mum'of the year you might win that. I spot a bit of the green eyed monster.
