The 52-year-old has copied most of his routine from his 86-year-old mother Julie, Sun online reported.
"He takes care of his skin, doesn't want to get old. He learnt it from Mum," Tony said.
However, it is doubtful that he developed an obsession with colonic irrigation, botox and blood regeneration therapies but his brother denies them all.
Tony said that Cowell loves black and white colour and his house also depicts the same.
