The model tells her Twitter fans they have 'no idea what goes on behind closed doors'
The fan asked why Katie, 35, had congratulated Pete and his girlfriend Emily MacDonagh on their pregnancy news on Monday when she’s previously said she wants to get back at the singer.
But Katie – who’s also expecting a baby with third hubby Kieran Hayler – insists that’s not what she’s looking for.
‘I’ve never used the word revenge on anybody thankyou you have NO IDEA what goes on behind closed doors so don’t judge,’ Tweeted Katie.
Katie is currently locked in a bitter legal battle with 40-year-old Peter, who she divorced in 2009 after four years of marriage.
Some Twitter users have questioned why she hasn’t dropped the case if she’s genuinely happy for him and Emily, 23, but the mum-of-three has no plans to do that.
‘no chance what I’ve had to go through needs to be dealt with and deserve my justice,’ Tweeted Katie on Tuesday.
