Yesterday (18 August), we told how Katie and Kieran had welcomed Jett into the world last week following what had been a rather tough pregnancy.
Before their boy was born, Katie was taken into hospital while enjoying a European road trip as her amniotic sac had torn.
Thankfully, all is well and Katie has now taken to Twitter after being inundated with messages of congratulations.
In a tweet posted by her brother, Katie said: "Many thanks for all your kind words of support and congratulations. Kieran and myself are so happy with our baby Jett.
"We look forward to coming home when allowed and introducing him to our families xx"
Later, she managed to type another message herself and added: "Finally in a state to tweet, thank you for everyone's amazing support and messages!
"I love @kieran0322 and our amazing baby boy Jett. #jett."
In February, Katie revealed she and Kieran were expecting their first baby together.
During her pregnancy, Katie openly spoke about suffering from bad morning sickness and how she had got a low iron count, which left her feeling exhausted.
