"He married Canadian Andrea Bertorelli in 1975. They met as students in a drama class in London. They had a son, Simon Collins (September 14, 1976), and Collins adopted Bertorelli's daughter Joely Collins (August 8, 1972), now a Canadian actress. They divorced in 1980, after she started an affair with their painter and decorator. Collins later appeared on the BBC's Top of the Pops singing his 1981 solo hit "In The Air Tonight" with a pot of paint and brush positioned near his piano. Collins has since claimed that the presence of the paint and brush was coincidental."
