Bryan Adams once half sat on my knee to talk to Rachel Hunter just after she'd split up with Robbie Williams. This was going to be a key chapter in my autobiography and now he's ruined it. Don't @ me.

I don't have any other memorable celebrity encounters - apart from the Richard Harris one - so I was clinging to this. It was going to be crucial.

Now remembering the time I met James Barry at a function and enthused at him for five minutes before noticing that Billy Zane... in a white tuxedo .... was chatting up my wife and both of them were getting on rather too well.

The trauma of that might have displaced the Bryan Adams story in my head and given it greater prominence than it deserved

Everyone is now sharing their random celeb encounters.
