Katie, 36, is expecting her fifth child and was pictured leaving the FUBAR Radio studios, having presented her new three-hour show.
Embracing the summer, Katie opted for a pair of pastel patterned trousers and she covered her blooming tummy with a light blue top and pale pink jumper.
Proving her yummy mummy credentials, the former glamour model topped off her look with a statement necklace, hair clip and a pair of pink retro shades.
This was Katie's third time on the airways since her show, which she co-hosts with Mark Dolan, launched - and it was as interesting as ever!
During her time on the radio yesterday, Katie opened up about her childhood sex attack in a park and gave fans an update on her marriage woes with husband Kieran Hayler.
Katie had previously announced that she would be divorcing Kieran after he slept with her best friend, however he is receiving help and Katie is standing by him - for now.
Meanwhile, Katie spoke about how Kieran has been offered the chance to appear on Celebrity Big Brother, and she even let slip how much his fee would be...
Katie unexpectedly found out she was six months pregnant back in May, just days before she learnt of Kieran's affair, but the baby - a girl - is doing well.
Last year, the soon-to-be mum-of-five gave birth to son Jett prematurely, but speaking about her latest pregnancy she said: "I haven't got long with this one. She weighs nearly four pounds, which is good."
