And now Jett and Bunny's father Kieran Hayler has spoken out about his ex-wife's headline-grabbing antics.
Katie's recent holiday was eventful to say the least.
While in Turkey, she reportedly dumped fiancé Kris Boyson via text, before flying new toyboy Charlie Drury out to join her and the kids in the sun.
Kieran told New!: "Katie's obviously not going to talk to me [about Charlie]. I don't think anyone knows what the truth is apart from those two."
Speaking about his kids, Kieran revealed they had "a great time" on the holiday.
All Jett and Bunny have said is that they had a great time.
He said:"All [Jett and Bunny] have said is that they had a great time. They raved about it and that made me think they were unaffected by who was there and what went down, which is all I can ask for."
Kieran also explained that Katie had just got the dates mixed up and didn't realised the siblings were due to start school the day before they got back from Turkey.
The father of two, who is loved-up with new girlfriend Michelle Penticost, also revealed that he hopes their children will remain unaffected by his former wife's love life.

He added that he understands he and Katie will have to "address it" when the kids start asking questions.
Kieran said: "We'll have to address it if it does come up, whenever that may be – I'm not going to lie to my kids."
Kieran's comments came as he revealed his "friendship" with Katie's ex-husband Peter Andre. He also spoke of their "very similar" parenting styles.
