Katie Price is to divorce her third husband little over 16 months since they married, according to a message posted on her Twitter account.
The glamour girl turned businesswoman announced only days ago that she was pregnant with her fifth child, and her second with stripper husband Kieran Hayler.
But in a series of messages she posted online, 35-year-old Katie told her fans: "Sorry to say me and kieran are divorcing."
Airing her upset to the world via Twitter, she wrote: " No human being deserves this especially being 6 months pregnant."
Another message added: " Worse pain in the world."
A spokeswoman for Katie did not wish to comment when asked about the messages posted on her account, which also made allegations about the reasons for the breakdown of her marriage.
It is the latest chapter in the colourful world of Katie who has previously been married to singer and TV personality Peter Andre and the Celebrity Big Brother contestant and cage-fighter Alex Reid. She and Alex separated in January 2011 after being married for less than a year.
Katie and Kieran had their first child together, Jett, in August last year. She also has two children, Junior and Princess, from her four-year marriage to Andre and a son Harvey from her brief relationship with footballer Dwight Yorke.
In a magazine interview this week she had told how she learned she was expecting on returning from a holiday in Cape Verde.
She told Now magazine that they thought she was just a few weeks pregnant when the couple went for a scan the following day.
"We were lying there... then this picture flashed up on the screen and we saw this enormous baby," she said.
"I was in shock, he was in shock - even the doctor was in shock. I was still in size 6-8 trousers... None of us could actually believe it."
A statement posted on her website said: "I appreciate most people will have seen my tweets on the subject of my marriage to Kieran.
"I make no apologies for them though it will be appreciated that, sending them immediately after Kieran confirmed to me what he had been doing for the last seven months, those tweets were a sign of my heart breaking. That he was doing it with a close friend of nearly 20 years is hard to understand.
"This statement however is from my head, not my heart. I am appalled that someone I loved, trusted and believed in has behaved in this way. If he had so little respect for our relationship I would have hoped he would have thought about our child, or the one that we have on the way.
"That he did not means he will no longer be part of my life. I will do all I can to ensure he maintains a relationship with his children should he want that. I am so grateful for the love of my children and family at this time."
Katie is reported to have been seen at Jane's house after heading round in dark glasses and hotpants, apparently to discuss the situation.
