What a great topic!
Best :
Tom Jones - yummo! He was just lovely and gorgeous and let me sit on his lap for a photo. Was tempted to throw my knickers at him but managed to restrain myself.
Kylie Minogue - petite, quiet and kept to herself. She just tapped away at her laptop for the whole flight (Syd-Mel) and said she had a lot of emails to catch up on. She was extremely unobtrusive and very pleasant.
Worst :
Shane Warne. Self-explanatory really.
