The 30-year-old, who is due to give birth in March, looked radiant in an emerald green printed shirt dress at Cosmopolitan's Ultimate Women Of The Year Awards.
Katie was all smiles as she made her way inside the venue at London's Victoria and Albert Museum, and kept a protective hand on her bump as she graced the red carpet to pose for photos.
She teamed her colourful outfit with black peep-toe shoe boots and accessorised with a chunky gold chain and a tan-coloured bag.
Earlier this month, Katie revealed the sex of her unborn baby, confirming that she would be having a baby girl with her boyfriend of two years.
The charity campaigner, who suffered severe burns in an acid attack in 2008, admitted last month that she felt she "lost the privilege" of having a child.
"I feel so lucky because for any woman it's a blessing to be able to conceive and carry a child," she told BBC Children In Need. "I had to keep saying to myself; 'it's real, it's really happening to me!'"
