Kieran Hayler thinks Katie Price "needs to put her kids first".
The 31-year-old star - who has split from Katie after being married to her since 2013 - says he is "doing fine" after they decided to go their separate ways but thinks his ex needs to focus on her five children - Harvey, 16, Junior, 13, Princess, 11, Jett, five, and Bunny, four.
He told Mirror Online: "I'm doing fine, I'm fine and pulling myself through, getting on with life, obviously Kate's not so good but I just want her ... good luck to her, do you know what I mean? She needs to put her kids first, that's all she needs to do."
Meanwhile, it was recently revealed Katie has introduced her children Bunny and Jett to her new man Alex Adderson.
A source said: "Alex is very much a part of Katie's life and has stayed over at the house when Bunny and Jett have been there, so he's met them. She's only introduced him as a friend but they've met him. It might seem quick to most people but she's really loved up with him."
Katie only recently started dating Alex, 25, after splitting up with Kris Boyson, 29, and she is said to be smitten with her new man.
An insider added: "Katie's relationship with Alex is still surviving even though she's in rehab and even has her family's blessing now. He has bought Katie a new car, a black Range Rover. The car is in his name so that it can't be used in her bankruptcy case, unlike her other possessions such as the pink Range Rover she's struggling to sell. Katie now drives the black Range Rover when she goes to her sessions at The Priory and visits Alex on her way home from rehab most nights. Things are really heating up between them and it's been so good for her to have someone to rely on while she goes through rehab."
