Katie Price texts Peter Andre on holiday in Cyprus day and night
Our source tells us that Katie initially contacted Pete, 39, with texts about their kids Junior, seven, and Princess, five.
A few messages also mentioned Harvey, 10 - her son with Dwight Yorke - who Pete thinks of as his own.
But the messages soon changed.
'Pete wouldn't reveal what the texts said,' says the insider.
'But what was most annoying was the frequency of them and the fact that they were being sent in the middle of the night.
'It was like Katie didn't want him to rest.
'He was always on guard, ready for the next time that his mobile phone would go off - he knew it'd be more stress from Katie.
'Emily wasn't used to it and was really upset.'
When Now approached Jord's team, a spokesman said: 'There's no truth in accusations that she's texted Peter on the subject of Emily.'
However, when we pointed out that Pete hadn't revealed the content of the messages but had been upset by the frequency, the rep refused to comment further.
