She's one fifth of The Saturdays, got two adorable babies and is married to rugby hunk Ben Foden.

The 33-year-old and Ben, 29, celebrated their third wedding anniversary this week, and she posted some amazing throwbacks on Instagram to celebrate.

Alongside the collage, Una wrote: "#TB 3 Years ago today #bestdayofmylife #benuna #wedding #anniversary [sic]."

Ben also shared a touching throwback, adding: "Can't believe 3 years have past since this day! Love you @unafoden my wife and bestest friend! #luckyme #wifey [sic]."

Una and Ben, who married in Ireland in 2012, are parents to daughter Aoife Belle, two, and five-month-old son Tadhg.

Speaking to OK! Online about their latest addition recently, Una said: "It's amazing. We have one of each now.

"Last night he actually slept for nine hours which was amazing. He's just smiling all the time. Even if you're really tired his little face just numbs the pain."

Ben added that they've taken inspiration from Magic Mike XXL to keep the excitement alive.

He said: "Learning new tricks from Channing [Tatum] and the boys. That'll spice things up."
