The 'Atomic Kitten' star, who has four children from her previous marriages and three-month-old daughter Dylan-Jorge with the former rugby player, said she plans to have more kids, reported Contactmusic.
"George wants to have another baby soon because he doesn't want to be an older dad and we'd like the children to be close in age," she said.
Katona's comments come just days after Kay was detained under the mental health act last week after a public meltdown, which he has blamed on a mixture of alcohol, steroids and sleeping pills.
