The 38-year-old, who has two children, Junior, six, and Princess Tiaamii, four, with Katie, 33, and also acts as a stepfather to her other son, Harvey, hated seeing his kids with his ex-partner's new boyfriend Alex, and woke up in the middle of the night worrying about it.
In an interview on British TV show, Piers Morgan's Life Stories, Peter said: 'It killed me, that night I woke up about two in the morning and I felt like I had been hit on the head with a hammer. I started to panic. It was horrible.'
Andre also added that he still loves his ex-wife Price, who he divorced in 2009, because she is the mother of his kids - but he still feels 'tortured' by their failed relationship.
Asked by Piers if he still loved the glamour model, he said: 'As the mother of my children, yes.
'I've moved on in leaps and bounds in one way but in another way, I'm still a bit tortured inside.'
