KATIE PRICE REVEALS WHY SHE'S FORGIVEN KIERAN AND WON'T TAKE REVENGE
Wife Katie Price, who is also mother to 11-year-old Harvey from her relationship with Dwight York and 9-year-old Junior and 7-year-old Princess from her marriage to Peter Andre, has also only shared a handful of pictures of Jett.
The couple have not revealed their new baby's name or face, and are currently working on patching up their relationship problems following Kieran's cheating.
Katie, 36, recently revealed she was giving her marriage another chance, explaining:
"A lot of people have passed comment on my decision to stay with Kieran and work on our marriage after he cheated on me with two friends.
"And there are obviously good reasons for me to stay with Kieran. I love him. But believe me, he hasn't had it easy."
"Kieran has changed so much. He's continuing with his therapy… I've got a good feeling about the rest of the year."
