Emily MacDonagh has been Peter Andre's rock through recent hard times
However, once again, his bitter ex-wife Katie Price appears to be doing all she can to ruin the festivities.
Pete's still in mourning for his beloved brother Andrew, 54, who died in December after a battle with kidney cancer.
But now he's being confronted with the fact that Jordan's third hubby Kieran Hayler - a stripper who she'd been with for a matter of weeks before marrying him - is making a very public attempt to become a 'father figure' to his two children, Junior, seven, and Princess, five.
Last week, the singer was left 'heartbroken and fuming' when Kieran Tweeted a picture, believed to have been taken by Jordan, 34, of him cooking with the kids.
It was captioned: 'Pancakes with the family!!!!!!!!'
A source close to Peter tells Dan Wootton: 'Katie knows it was something that'd hurt Pete more than anything else in the world.
'He's done everything he can to protect his children from her various blokes.
'To him, this is sickening.
'How on earth can Kieran say Junior and Princess are family after just a few weeks of knowing them?
'He doesn't understand why Katie can't let him just be happy.'Jordan's rep declined to comment.
