The new mother appears to have been enjoying family time with third husband Kieran Hayler, 26.
Katie, 35, shared a picture of Jett sleeping in his Moses basket last night, though she kept his face covered.
‘Baby Jett fast asleep while me and hubby @kieran0322 watching tv in bed eating chocolate and drinking a cuppa tea,’ she wrote.
The model then added a picture of what appeared to be a cushion cover, with the words 50% Katie 50% Kieran 100% Jett, stitched in.
The couple have hardly been spotted since returning from Europe, where Katie was forced to give birth 8 weeks early, after her pregnancy ran into complications.
At the beginning of the week they were seen heading to the doctor to check on Kieran’s recent injury, although the happy twosome were careful to cover their baby carrier with a blanket.
The recent pictures on Twitter come shortly after Katie- also known as Jordan- revealed that the person responsible for blackmailing her over stolen nude pictures, was arrested at the beginning of the week.
The reality star revealed on Twitter:
‘Somebody has been arrested and charged about blackmailing to use these stolen pictures so a step closer to who stole them’.
‘For the record im NOT worried about any sex pictures and it's NOT affecting my relationship, I'm sure ...... would be worried’.
