The Saturdays' Una Healy Flaunts Post Baby Bod In Summer Dress

It was back to work for new mum Una Healy last night as she filmed her first TV appearance since welcoming her daughter into the world.

And it was hard to believe The Saturdays star gave birth to Aoife Belle just over a month ago, as she showed off her amazing post-baby figure at the recording of Keith Lemon's Lemonaid.

Una flaunted her new frame in a fitted green and white summer dress teamed with a pair of summer sandals and was clearly not bothered about how flipping freezing it was.

She was joined at the London TV studios by her bandmate Mollie King - who is rumoured to be dating Prince Harry.

Una was also putting all the recent scandal surrounding her fiance behind her, after he was filmed dancing naked with strippers on his stag do.

The incriminating footage showed Ben dancing with the girls after having his jeans and boxers pulled down.

A source told The Sun: "Ben and three other lads were on a rotating stage with this topless girl in the middle. Another girl reached in and pulled down his jeans and boxer shorts. Ben waggled his crown jewels at everyone.

"There was a lot of laughter and cheering. In fairness I think he then maybe thought better of it and covered his parts up."
