Katie Price believes she owes it to her son Jett and unborn daughter to support their father, her third husband Kieran Hayler, as she seeks help for his issues following his affair with her ex-best friend Jane Pountney.
The sexy star - who is pregnant with her second child with her cheating spouse - is supporting her husband through treatment for ''historic issues'' because she wants him to be a ''positive influence'' on their kids, though she is still unsure whether their marriage has a future following revelations he cheated on her with her best friend Jane Pountney and a mystery other woman.
Writing in her Now magazine column, she revealed: ''Kieran's undergoing treatment with respect to some historic issues.
''He's the father of one, and God willing, soon two of my children. I feel I owe it to them to stand by him and support him in his efforts to resolve his issues so he can be a positive influence in our lives.
''What that means for me and Kieran long-term, I have no idea. I'll help him where I can but what the future holds is impossible to say.''
Katie - who has son Jett, 10 months, with Kieran, and kids Harvey, 12, Junior, nine, and Princess Tiaamii, six, from previous relationships - is trying to focus on her pregnancy for now and says her other kids can't wait for the new arrival.
She said: ''My bump - or the third boob as Harvey likes to call it - is developing very well.
''Both Princess and Junior can't wait for their new sister to arrive and are already whispering their hellos and sending kisses. As for Jett, well, he's just dribbling with anticipation at the moment.''
Take a look back at October's inaugural event.
The film is expected to continue without Mendes' involvement.
