Katie, 30, is due to give birth in March and is now stocking up on all things pink after revealing the sex of her unborn child in an interview.
It will be a first child for the star and her boyfriend, who likes to keep his name out of the spotlight.
Last month, Katie - who suffered severe burns in an acid attack in 2008 - spoke about her pregnancy and admitted that she was worried she'd "lost the privilege" of having a child.
In an interview for BBC Children In Need, Katie said: "I feel so lucky because for any woman it's a blessing to be able to conceive and carry a child, and to be honest, there was a time in my life when I thought I'd lost that privilege.
"I had to keep saying to myself; 'it's real, it's really happening to me!'"
Last week, Katie showed off her baby bump as she picked up a prestigious prize at Best magazine's Bravest Women Awards in London.
