I had Ronan Keating on board on Sun going to Portugal.... he kept a low profile, he was travelling with his wife and little daughter.... polite and very, very good looking!
Couple of months ago I had on board Caprice, the american model or whatever she is, she was in Celebrity Big Brother.... she was travelling all her own, ignored everyone, put her head on the tray table and slept for the duration of the flight.... cant really say anything bad about her!
