The showbiz parents are already parents to baby boy Koa, who is 18 months old. And while Kian definietly wants to add to his brood with wife Jodi, the couple's busy schedules means that plans will have to be put on ice, for the short-term at least.
With his second stint on the Voice Of Ireland coming to an end, the former Westlife star says his busy working schedule is not slowing down.
Ex-Hollyoaks and former Wonderland star Jodi (29) gave birth to the couple's first child in December 2011.
She has spoken about being happy to forgo her singing career to remain a stay-at-home mum, but is now looking forward to going back to work, according to her hubby.
"We're definitely not having another in the near future," Kian told the Diary. "Jodi is making a move back to work and she has two big offers on the table, so that is our main concern for now,"
Kian and his English wife currently divide their time between London and his native Sligo, as the blond crooner juggles work commitments in Ireland and the UK.
"Neither of us have time at the moment but, at the same time, we're not going to leave it too long," Kian explained.
"We're both still young and don't want there to be a huge gap between the kids. We would like Koa to have a little brother or sister to play with," he added.
The 33-year-old is currently in talks about more work projects with ITV in the UK. Since Westlife came to an end after 14 years last June, the singer has been in high demand.
He has enjoyed slots on This Morning, with ITV, as well as presenting The Hub for the channel. He is currently working from his Sligo mansion in scenic Strandhill.
"There are too many things in the pipeline to head off on holiday when the Voice is finished," Kian added.
Jodi's singing career will remain on the shelf for the time being following the end of girl band Wonderland.
But Kian says she wants to get her teeth into acting again. "It will be acting rather than singing. It's been awhile for her, so I think she would like to give the acting a go again.
"She is still in talks, so I can't say too much, but there are definitely two big offers on the table."
