Taking to Instagram following their outing, the Irish star shared a sweet family snap of herself and her children for fans to see. Aww!
In the photo, Una (who makes one very cool looking mumma!) can be seen pushing her baby boy in his pram while her two-year-old Aoife hitched a ride.
Sporting trainers and her hair in a ponytail just like her mum, Aoife looked every inch Una's mini-me during their Sunday walk. Cute!
Una's latest photo comes a month after she and her rugby pro husband Ben Foden welcomed their newborn Tadhg. Shortly after the Irish beauty gave birth, Ben confirmed the safe arrival of their son on Twitter.
He tweeted: "Tadhg John Foden has been born! Mum and baby are both amazing and healthy. He has a full head of hair and his mummy's lips! #babybenuna."
Una then thanked fans for their well wishes, revealing she is "so so so in love" with her baby boy.
While the couple are yet to share a photo of their new arrival on social media, Una's bandmate Mollie King gave us all a glimpse of baby Tadhg last week.
After paying a visit to her pal, Mollie posted a photo of herself enjoying cuddles with Una's newborn to Twitter, telling her followers she had had the "best day" meeting the latest addition to the Foden family.
She said: "Had the best day yday with @UnaTheSats! Got a performance from Aoife of Frozen & a cuddle with the little man himself."
Unsurprisingly, fans were quick to comment on just how gorgeous Tadhg is.
One user said: "My heart is melting." While another wrote: "Aww what a beautiful boy."
We think so too!
