The Wannabe hitmaker will be the star guest at a special ceremony at The Savoy hotel in London next month (03March13) alongside six other mothers who will be honoured for their tireless efforts to improve their communities.
Chisholm, who is mother to three-year-old Scarlet with ex-partner Thomas Starr, admits juggling parenting with her pop career is hard but credits her daughter with boosting her confidence.
She says, "I am so much happier, more confident and courageous and it's all thanks to Scarlet. Being with my family is the most important thing in my life... Being a mum might not be easy but it's definitely the most rewarding job in the world.
"There are millions of inspirational mums out there, doing incredible things to help others. It's fantastic to be involved with something that celebrates this."
The Tesco Mum Of The Year Awards ceremony will air on U.K. Tv on 10 March (13).
