The 'All Fired Up' star was all smiles as she displayed her pregnant curves.
The Saturdays' Una Healy showed off her baby bump during the band's appearance at Capital FM's Jingle Bell Ball over the weekend.
The pregnant star, who is expecting her first child – a girl – with England rugby star boyfriend Ben Foden, was all smiles on the red carpet.
Despite being due to give birth early next year, the 'All Fired Up' singer showed no signs of slowing down as she danced away during The Saturdays' performance.
In a recent interview, Una admitted that she was excited to be having a girl.
"I come from a family of girls, I went to an all-girls school and I'm in a girl band, so I guess it's fitting that I'm having a daughter," she said.
The Saturdays were one of a host of artists who performed at last weekend's Jingle Bell Ball at London's O2 Arena.
