The star's mother Rhonda was diagnosed at the young age of 52 and her son has since become a proud ambassador for the detrimental disease.

"This year she [his mum] turns 60 and we are having to face placing her into full-time care to ensure she is getting the care she needs," the 29-year-old said.
