Not only does she have two adorable children, she’s also married to the gorgeous Ben Foden, 29.

So we don’t blame her for wanting to show off her family.

The Saturdays’ singer, 33, gave birth to their second child last month, a son called Tadhg, and she took to Instagram this week to gush over him.

Posting a snap of Ben holding his son, with Tadhg gazing curiously up at him, Una wrote: “My heart could burst with how in love I am x”

She then shared one of Tadhg lying contently in his crib, adding: “5 weeks old”

Earlier this month proud dad Ben uploaded a photo of him with his very smiley son. He wrote: “Still up with this little side! He’s turning into a little night owl #lovehim #theman [sic]”

Could we be more jealous of this family? Probably not!

Ben and Una, who are also parents two-year-old daughter Aoife Belle, recently opened up to Hello! magazine about Tadhg’s arrival.

Rugby star Ben said: “The second he was out, I abandoned poor Una and all my focus switched to Tadhg. I did my own check on him and cut the cord, as I had done with Aoife.

“Again, that was an incredible experience. I held him for a while, then I lifted him onto Una for the amazing skin-to-skin contact.”
