The mother-of-five took to Twitter on Monday afternoon to share her excitement- presumably over her upcoming nuptials to partner George Kay, 34.
The 33-year-old, who has daughters Molly, 13 and 11-year-old Lilly from her marriage to singer Brian McFadden, 7-year-old Heidi and 6-year-old Max from her marriage to taxi driver Mark Croft, and baby Dylan-Rose with Fiance George, tweeted excitedly:
"Omg omg omg 13 days and counting @mrgsjkay crazy!!! Love you xxxx".
The Atomic Kitten star, who performed at the Blackpool Illuminations concert on Sunday, also shared pictures of her oldest daughter's 13th birthday.
The reality TV star had previously tweeted: 'Dear Daughter, I could not be more proud of the beautiful, caring and talented young woman you have become. May all of your wishes come true'.
