Katie Price and Peter Andre to split

Reality TV stars Katie Price and Peter Andre, whose relationship began when they were contestants on I'm A Celebrity ... Get Me Out of Here!, are to separate.

A spokesman for the couple confirmed today that they were separating after four and a half years of marriage.

Price, a former Page 3 model, and Andre, who enjoyed chart success as a singer in the 1990s, began a relationship after being contestants on 2004's I'm A Celebrity and were married the following year.

Since that time the pair have generated an enormous volume of publicity, including their ITV2 shows When Jordan Met Peter, Jordan & Peter: Laid Bare, Jordan & Peter: Marriage Mayhem?, Katie & Peter: The Baby Diaries and Katie & Peter: The Next Chapter.

Their latest ITV2 reality TV show, Katie & Peter: Stateside, is currently attracting more than 1 million viewers on Thursday nights.

Formerly known as Page 3 girl Jordan, the first volume of Price's memoirs, Being Jordan, sold more than 1m copies. The third volume of her memoirs, Jordan: Pushed to the Limit, was published last year.
