As we've come to expect, Katie, 35, kept her growing baby bump covered with a loose scarf as she arrived at the Sanctum Soho Hotel for the Easilocks event on Tuesday evening (9 July).
She has said on several occasions during her pregnancy that she wants to be more private this time around, which includes keeping her bump under wraps.
Katie, who is known for her love of elaborate outfits (a princess costume for her book launch, a giant pair of lips at her perfume party...), looked understated and chic in her blue jeans, gold wedge sandals and white T-shirt.
Kieran, meanwhile, in a matching jeans and white top look, appeared to have had an accident as he wore his right arm in a sling, although neither he nor Katie have said what happened.
After mingling with fellow guests including Lucy Mecklenburgh, Amy Childs and Chantelle Houghton (who was engaged to Katie's ex-husband Alex Reid), parents-to-be Katie and Kieran headed to dinner with friends in Soho.
Kieran was seen protectively clasping Katie's hand as they walked from the restaurant to the car, and the couple appeared to be in good spirits as they sat giggling in the back of their taxi.
Earlier in the day, Katie had revealed she was "gutted" to have been forced to cancel an upcoming promotional trip to Australia on her doctor's orders.
The model explained she'd experienced difficulty breathing lately and had been feeling faint, so after an examination, her doctor advised no long-haul flights.
She told fans: "I'm devastated I'm not going to be able to make my Australia trip now due to health reasons. I promise I will come soon and it's been a year of planning but I can't risk my babies health and my health is something I can't control."
Katie had been due to launch her first couture shoe line, Katie Price – The Gold Collection By Sistar Shoes.
The star, who married Kieran in The Bahamas in January following a whirlwind romance, announced her fourth pregnancy earlier this year. She is already mum to sons Harvey, 11, and Junior, 7, and daughter Princess, 6.
