It's hard enough just to share screen-time with British bad boy Simon Cowell, so imagine what it was like for The X Factor judge's younger brother growing up with him.
After spending 50 years putting up with the King Of Mean, Tony Cowell has revealed in an exclusive interview in the new issue of Star magazine that his big bro wasn't any sweeter as a child than he is on prime time.
"Growing up with Simon was hell," the correspondent for ReelzChannel told Star. "He was like that kid Damien from the film The Omen. He was a really difficult child."
The reality guru went from a stubborn, know-it-all kid, to a wild teen, said Tony. "He was a naughty teenager...drinking and smoking at an early age."
Much to the relief of millions of fans, Simon dropped his rebellious ways when he began working in the music industry, and the rest is TV history.
