Katie, 30, is expecting her first child with her boyfriend in March and it's fair to say she is looking blooming marvellous.
The mum-to-be dressed her growing tummy in a floor-length black gown, featuring a metallic gold sash across her right shoulder, before walking the red carpet at the Sun Military Awards.
Katie accessorised her maternity outfit with a simple gold and black clutch bag and a pair of gold peep-toe heels, and she wore her blonde hair in an up 'do.
During the event, which was held in London, Katie posed for a picture while placing her hands on her baby bump before sharing it on Twitter.
Alongside it, Katie commented: "Brilliant night at #TheMillies paying respect to out troops, veterans and really heroes."
Katie, who suffered serious burns in an acid attack in 2008, announced her pregnancy in September, saying: "I just want to shout it from the rooftops!"
Last month, as reported on Reveal.co.uk, Katie confirmed she and her boyfriend - who likes to stay out of the spotlight - are expecting a baby girl.
