The 48-year-old singer refused to go on the road for 17 years because he was so "freaked out" by the worldwide sales of his 1987 debut solo album `Faith` and admitted he had no idea how to deal with the level of fame he achieved.
He said: "I was so scared of touring because of my experience with `Faith` and the sheer size of it all. I was half the age I am now and `Faith` had been number one in America two Christmases in a row - that`s kind of unheard of - and it was frightening.
"It seems strange that I turned my back on it, but that year more Americans bought my album than Michael Jackson`s `Bad` and that, for a 24 year old who was single, closeted and very lonely, freaked me out."
George is currently on tour with a 41-piece orchestra and admits the scale of the shows made him nervous for the first time in many years.
He told Britain`s Hello! magazine: "I`ve always believed I`d do some kind of orchestral tour because it`s such an obvious challenge. But it`s the first time I`ve been nervous doing live shows, which is odd as I wasn`t nervous about the first Wham! shows."
Emma Stone thinks Hollywood is growing more conservative.
The `Help` actress believes many movies that were made in the 1970s would not be commissioned these days as studio bosses are too afraid of "offending" anyone.
She said: "It concerns me that movies seem to be getting more and more conservative and watered down.
"I see movies made in the 70s such as `Network` that I really don`t think would get made today. A movie that calls the audience to task for sitting glued to their screens, believing everything they`re told by the media? That would be considered too challenging today. Nobody wants to risk offending the viewers.
"Movies need broad appeal to succeed and bosses don` want to alienate anyone."
Emma, 22, believes many actors censor themselves to an extent where it has a severe impact on their performances.
She added: "I even hate it when people censor themselves. You can always tell when an actor has grown a `rhino skin` to protect themselves. It comes across on screen and they aren`t believable.
"They`re dead in the eyes because they`ve been told a million times that they`re the greatest actor that ever lived. If you don`t realise what`s happening and get your feet back on the ground, it can be the worst thing that ever happens to you."
