Una has been enjoying a sunshine break with her rubgy hubby Ben Foden, and posting some happy snaps along the way. She captioned this bikini photo: 'Holiday Pose! #cheesy'
It's hard to believe the star has two children with a tummy that taut, but Una has spoken out in the past about her struggles to lose the weight she put on with her first child, daughter Aoife Belle, who she gave birth to in March 2012.
'I'm aware I'm getting a bit older and after having a baby I have to work harder', she told Women's Fitness magazine.
'My abs were the hardest part to tone after pregnancy. My tummy felt like jelly for a while and it's much more difficult to tone than it used to be.'
Well whatever she did the first time around certainly seems to have worked for the second, you look amazing Una!
