The TV star - who has three children, Harvey, eight, Junior, five, and three-year-old Princess Tiaamii, from two relationships - has made the 20-person shortlist for this year's accolade along with the former Spice Girl and the 'x factor' judge.
The trio have been nominated for the way they have coped with the demands of parenthood while also managing their successful careers and handling the pressures of fame.
They will compete against 17 other star mothers, including Billie Piper, Charlotte Church, 'Britain's Got Talent' judge Amanda Holden, Kerry Katona, last year's winner Holly Willoughby and surprise inclusion Queen Elizabeth II.
Noel Rowse, Managing Director of Foxy Bingo who are sponsoring the prize, said: "We are thrilled to be the official sponsor of Celebrity Mum of the Year 2011 and can't wait to see who takes the crown this year. Sponsoring the award allows us to celebrate mums across the nation, encouraging them to treat themselves, after a hectic day's work juggling family life, and enjoy a little 'me' time with Foxy Bingo."
Voting is now open for the prize, which is in its 11th year, and you can choose who you think should be crowned the winner at www.foxybingo.com/celebmum.
You can register your vote until Sunday March 27 and the winner will be given her award at an exclusive presentation ceremony at the Renaissance London Chancery Court Hotel on Wednesday March 30.
