Katie Price is believed to have banned Peter Andre from posting pics of their kids on social media.
The former married couple have two children together, Junior, 13, and Princess, 11.
They have reportedly been at odds over their approaches to parenting, with Katie wanting to get the youngsters involved in her reality TV show, My Crazy Life, and Pete keen to keep them away from the cameras.
It follows Katie's appearance on Good Morning Britain earlier this month, during which she launched a scathing attack on her ex in a discussion about their children.
She fumed to co-hosts Piers Morgan and Susanna Reid: "I'm actually really cheesed off with Pete at the moment because when people are watching my show they're going to think, 'Where's Junior and Princess?'
"He won't allow me to film with them. He won't allow me to do photo shoots with them. He's being such a hypocrite."
According to a source quoted by New! Magazine, what we've seen on our TV screens is just the tip of the iceberg in the escalating feud.
They told the publication: "Pete thinks Katie has lost the plot and was trying to make him look bad by calling him out on live TV."
He won't allow me to film with them. He won't allow me to do photo shoots with them. He's being such a hypocrite.
The source went on to claim that Katie "went ballistic" when Pete asked her not to feature the kids in her reality show, since the producers will want them involved to boost the ratings.
In a bid to get back at Pete, the source suggested that Katie has taken a similar stance and banned Peter from sharing pics of their children online.
They continued: "Kate said that he could no longer [post] pictures of Princess and Junior on social media pages. Pete agreed, which Kate didn't see coming."
ED! has contacted Katie's reps for comment.
Peter was on Good Morning Britain earlier today.
Things got a bit awkward when the Mysterious Girl singer, 46, was shown a clip of Katie slamming him over his stance on their kids.
Piers then asked him for his thoughts on the situation, but Pete shut the conversation down by telling him: " Piers, you should know by now that I don't talk about these things publicly. I never have. Why would I do that?"
