The past and present 'Big Brother' presenters have both been selected as nominees for the 13th annual award - which will be voted on by the public on the Disney for Mums UK Facebook page - with the winner being announced next month.
Disney UK's Anna Hill said: ''Being a mum is always a juggling act and we want to recognise the celebrities that the public think are making a great job of it.''
The Saturdays singers Frankie Sandford, Una Foden and Rochelle Humes will also be competing against each other for the prize, with 'Strictly Come Dancing' winner Abbey Clancy, 'Britain's Got Talent' judge Amanda Holden, Denise Van Outen, Michelle Heaton and 'Young Blood' singer Sophie Ellis-Bextor completing the list of nominations.
The famous mothers have a total of 15 children between them but Disney also wants to make normal mums feel a bit more special in the run up to Mothers Day in the UK, March 30.
Anna added: ''As well as crowning the Disney Celebrity Mum of the Year, we'll also be celebrating great mums from across the UK in the run up to Mother's Day. All mums need a bit of recognition every now and then, whether they're in the spotlight or not!''
Last year's winner, Spice Girl Emma Bunton, spoke about how important the award was to her, saying: ''This award is extra special as it's voted for by you the British public, and of course is about the most important thing - being a mummy!''
