The 34-year-old Atomic Kitten singer was reported to have cancelled a family holiday to Cape Verde this Christmas because husband George Kay, 34, had been acting jealous and clingy, but she's now spoken out to rubbish the claims, reported Daily Mirror.
"Every girl dreams of finding her knight in shining armor, but not me...I've already got mine," she posted on Twitter.
Former rugby star George was detained under the Mental Health Act earlier this year after suffering a meltdown outside their Oxfordshire home, which he blamed on mixing alcohol, steroids and sleeping pills, and Katona was reported by a newspaper as questioning their relationship after he walked out on her during a number of arguments.
