Now she's insisting that their daughter is getting her own back on Kieran, for putting her mum through all of that stress.
Speaking to a British magazine, Katie said: "I had the most stressful pregnancy and they say babies sense everything, I think she's making me pay for it because she's more difficult than Jett!

"She's awake all the time and Kieran's like, 'Oh my God, what is she like?' And I'm like, 'Yeah, you caused me to be stressed and now she's punishing you!'I wind him up about it."
While baby Bunny might not have quite forgiven her dad, Katie is standing by her claims that Kieran has changed since news of his affairs came out.
She continued: "Now he's stuck by my side, and I know some people will say, 'He should have done after what he did,' but what's important to me is he's made a change and he hasn't slipped up at all.

"Kieran has changed. If he hadn't, then he would have been gone. It's onwards and upwards now."
Discussing her new daughter's unusual name, Katie said Bunny was a logical choice, because they already have Princess.
She added: "We couldn't call this baby something like Helen or Lisa, not that there's anything wrong with those names, but they don't go with Princess."
