The Australian singer is particularly worried about being accused of chatting up women on the Internet, and so he has vowed never to use popular sites like Facebook, MySpace and Twitter.
"Facebook is the most dangerous thing you can ever do. I will not go on it. I refuse," Stuff.co.nz quoted him as telling British magazine More!
"Twitter is bad too, but not as bad as Facebook because you go into people's pages and you talk to them."
"I was a good boy throughout my marriage, all the way. If someone sends you even the slightest hint, there's no excuse when you're married," he added.
