Katie, 36, is currently eight months pregnant with hers and husband Kieran Hayler's daughter but has revealed that she should be taking it easy.
However, refusing to put her feet up, Katie travelled to London earlier this morning (22 July) to appear on her weekly Fubar Radio show.
Last summer, Katie gave birth to hers and Kieran's first child together - a boy called Jett Riviera - and had a tough pregnancy too.
She ended up giving birth to him prematurely while on holiday in France and has explained that this baby could come before the date of her planned caesarean.
Katie told listeners: "I've got a date that I'm booked in for a C-Section that's a few weeks away, but because of an operation I had a few weeks ago it could happen anytime.
"Each pregnancy I've had has been completely different. I should be on bed rest but I'm just too busy."
Katie never fails to hold back during her radio show and, as always, today was no different. In May, Katie's world was left in tatters when she discovered her husband Kieran had cheated on her with her best friend.
During today's show, Katie spoke in depth about how he is undergoing therapy for a "sex addiction" but added that she is set to reveal ALL the details of her marriage troubles in a new book.
