Earlier, the singer, who met the former glamour model on the TV show in 2004, was moving to Australia for three weeks to work as a behind-the-scenes reporter for This Morning. But Katie's re-entry into the show has discouraged him. He has reportedly told the TV bosses that it would be totally improper for him to go ahead with it.
"Pete was really looking forward to going back to the jungle but as soon as he found out Katie was going to appear, he said there was no chance in hell he would go," the Daily Mail quotes a source. "He reckons there's no way he could speculate on Katie's antics and any outback flirtations in an unbiased way," the source added.
Peter has decided to stay at home and look after his and Katie's three children. However, the show will begin on Sunday night.
