Have to disagree about Elle MacPherson - I have had her on several flights and she was as quiet as a church mouse. Though admittedly, no pyjamas were offered and I don't speak a word of French. She did drink French champagne though, does that count?
Best celebrity would definitely be Tom Jones. He's a sweetheart and a really nice guy. Shame his entourage weren't as nice.
Kylie Minogue was also a sweetie. Signed autographs and had photos taken with the kids that were on board and was very gracious and polite.
