The 48-year-old, who has openly confessed that he’s homosexual, last year released a tell-all book entitled ''Life With My Sister Madonna''.
According to Ciccone, who declared in his book that the Queen of Pop is a control freak, a narcissist and a cheapskate, said the ''Striptease'' star stopped speaking to him when she met her now-husband Ashton Kutcher.
After meeting at a Los Angeles Kabbalah centre, Demi and Ciccone became firm friends.
However, when Demi's relationship with Ashton started to get serious, Ciccone claims she immediately dropped him, report the ‘China Daily’.
He told Britain's Observer newspaper: "A certain kind of diva carries a gay man around like a handbag, like an accessory. And then once they find the right straight guy, they don''t need a male companion any more."
This isn't the first time Ciccone has spoken out against the 46-year-old actress. Last year he revealed she squirted her breast milk at his lesbian friends during a night out.
He said: "We went out and Demi was dancing up on me and humping me from behind. The one part that's not in the book is that she was lactating at the time and she was squirting breast milk at my lesbian friends... the lawyers didn't think it was wise for me to print that."
