The former glamour model revealed that her son’s actions mean he is feeling “extremely settled” in his new surroundings at college.
19-year-old Harvey lives with complex health conditions including autism, blindness, Prader-Willi syndrome.
Katie shared her thoughts on the incident with OK! Magazine.
She said: “I said to the staff at the college, ‘I’m so happy that he’s done all this because now I know he’s really settling in.”
Earlier this year, Harvey was given a place at National Star residential college in Cheltenham where he has been living away from his four siblings and mum for months now.
Harvey receives round-the-clock care at the home and it is not the first time he has damaged his belongings as he has previously done so at his home which he shares with his famous mum.
Katie added: “They are now living and breathing what I’ve had all of these years.”
The mum-of-five admitted how much she misses her son since he moved away and tries to visit him in the Cheltenham college every weekend.
Katie is also mum to Junior and Princess Andre whom she shares with singer Peter Andre and Jett and Bunny who she had during her third marriage with Kieran Hayler.
Katie revealed her Christmas plans for this year, she said: “The plan is that Harvey will be home for Christmas and New Year. It will be me, Harvey and Carl.
“I don’t have the other kids this year as it’s their dads’ turns because I had them last year.
“And then obviously I’ll see my mum and my family. We’ll be at my house in Horsham – I’m back here for good and I’m loving it.”
