Apart from the occasional bump snap, Storm and Ronan Keating have been keeping mum about the details of their incoming arrival.
That was until the expectant mum (luckily for us) slipped up on social media!
Taking to Instagram, the Australian-born beauty shared the image of a sweet gift for the bub given to them by Ronan’s 11-year-old daughter Ali from a previous marriage.
In a now-edited caption, she wrote: "So @_alikeating surprised us with this gift for her baby sister/brother haha. Making sure they know their roots #Irish #BabyGift #Cute #LittleLeprechaun #LoveIt."
The 35-year-old had originally written “baby brother” before making her correction, but the blunder was not missed by followers.
"Love this... Excitement must have got the better of you #babybrain," commented one fan.
The newest member of the Keating clan will be the X-Factor Australia host’s fourth child, while it marks the first for Storm.
The exciting news was revealed back in December in a blog post on the producer’s site.
"On the 17th August in 2010, my husband and I became friends," she penned.
"On the same day five years later we became husband and wife. We're now very excited to announce that a year later (and again to the exact date) we became parents-to-be!! And so THAT'S why I passed on the mulled wine," she joked.
"Words cannot describe how overwhelmed with happiness we are."
Ronan and Storm first met through the talent show in 2010.
In August 2015, the couple tied the knot in a romantic ceremony in East Lothian, Scotland.
The 40-year-old was previously married for 17 years to Yvonne Keating. Now, they share their three kids Jack, 17, Missy, 15, and Ali, 10.
Storm parted ways with her ex-husband Sydney financial director, Tim Ivers, in April 2012.
