The Westlife singer and the former `Hollyoaks` actress are closer than ever following the birth of their son Koa in December and would love to give him a sister in the future.
Kian said: "A littlegirl would melt my heart now but every man likes the idea of having a little boy. I`m looking forward to taking him surfing, golfing - he`s going to be an outdoorsy little dude. But we do want a littlegirl, hopefully next time.
"I think no matter how many boys we have, we`ll keep going until we have a girl too!"
Jodi added to OK! magazine: "Kian has said he wants four children but I don`t know about that. If he`s putting the pressure of four on me, I`m going to put the pressure of a girl on him. I`ve got my little boy. I wantgirl next but not any time soon."
Kian also revealed Westlife manager Louis Walsh - who doesn`t have any kids of his own - has surprised him by his interest in the baby.
He said: "Louis hasn`t seen the baby yet but he does continuously ask about him, which is so sweet. Louis doesn`t strike you as the type of person to talk about children much, yet he`s asking loads about Koa. Maybe he`s getting soft in his old age."
Kian is preparing for Westlife`s final tour and admitted he and Jodi are looking forward to taking some time off to travel the world with Koa.
He said: "Jodi and I would like to get back to the sunshine and spend some time travelling and living a lifestyle that we haven`t lived in a few years. We`d love Koa to see the world, having a baby really puts things into perspective."
