Last week, Katie gave birth to her baby boy after being rushed into hospital during a European road trip with husband Kieran.
The mum-of-four hadn't had the easiest of pregnancies and was on holiday when her amniotic sac tore. She is still recovering from her emergency caesarean abroad.
Writing in her column for The Sun, Katie today said: "I'm still in Europe recovering from my own birth drama.
"Thanks to all fans and well-wishers who have sent messages since Jett's birth. He is doing great and is getting stronger every day."
Yesterday (22 August), Kieran shared the first picture of Katie following her son's dramatic birth.
The snapshot, which he posted to Twitter, shows the couple kissing and alongside it Kieran gushed: "It's been a tough 3 weeks but we are closer and more in love than ever before."
Katie has not revealed exactly where she is in Europe, but it's great to hear she and Jett are doing well.
