Chris - or Little Chris as he is also known - released a statement last night and thanked fans for all the supportive messages he has received since his mum Petra's death on Wednesday (14 May).
The reality star describes Petra as an "angel" and admitted that his "whole world has been taken away" from him.
Chris said: "Thank you for everyone's support at this time. I actually feel like my whole world has been taken away from me.
"She was a lovely lady and the best mum. She was the kind of lady who never stopped giving and truly cared about everyone. She was our angel."
Chris has also revealed that his family has followed Petra's wish of having her organs donated, so she can help other people.
"She was selfless in donating her organs and that's just how she was as a woman," Chris added.
Chris first revealed his sad news on Twitter shortly after his mum died on Wednesday. He said: "This morning mum passed away. Thank you for everyones support over this tragic time. She was a lovely lady & the best mum #RIPmum."
Two days earlier, he had told his fans: "Praying for a miracle." Chris also hinted at his mother's battle on 7 May, saying: "In a blink of your eye your whole life can change... Appreciate the people & loved ones around you."
