Model Katie Price announces on Twitter that she is to divorce third husband

Model Katie Price has announced on Twitter that she is to divorce her third husband little over 16 months since they married - she has accused him being unfaithful. Just days ago, the glamour-girl turned businesswoman announced she was pregnant with her fifth child, and her second with stripper husband Kieran Hayler.

But in a series of messages which she posted online, 35-year-old Price told her fans: "Sorry to say me and Kieran are divorcing."

She went on to claim he had been conducting an affair with a friend.

No human being deserves this especially being 6 months pregnant

Price concluded by adding: "Worse pain in the world."

A spokeswoman for the model did not wish to comment when asked about the messages posted on Price's account.

It is the latest chapter in the colourful world of Price 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 Reid separated in January 2011 after being married for less than a year.

She and Hayler 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."
