The Westlife singer took to Instagram to announce the couple - who are already parents to five-year-old son Koa and 22-month-old son Zeke - are expanding their family.
Sharing a picture of the baby scan next took a book called 'Your Pregnancy Bible', he wrote: ''Look at what wifie is reading again! Here we go again #jodialbert baby no.3 is on the way!!! (sic)''
Whilst Jodi captioned the same picture on her own Instagram account: ''Looks like I might be needing this again... baby no3 (sic)''
Meanwhile, Jodi previously confessed her and Kian would like to have ''three or four'' children eventually.
She said: ''It's hard to think about right now but Kian is from a big family of seven, so ideally we'd like three or four. The Irish have big families. We'd love a girl, but so long as they were happy and healthy, that's all that really matters.''
Asked how she felt when she learned she was expecting a second son, she added: ''We'd like a girl at some point but we just wanted a healthy, happy baby. I never dreamt before Koa of being a mum to little boys, but now I'm obsessed with boys - they're such cool little dudes. And I thought Koa needed a companion - Zeke even wore one of Koa's little baby grows in the hospital.''
