The 35-year-old "Atomic Kitten" singer split from third husband George Kay in October after 11 months of marriage after he was arrested for allegedly assaulting her.
The singer is now focused on living for herself and her kids, reported Female First.
"I am a single mum who doesn't need a man to make her laugh, wipe her tears, hug her tight, see her succeed, watch her fail, or cheer her on to make her strong. My kids do x (sic)," she wrote on Twitter.
