The British media is claiming that Catherine Zeta-Jones recently went to a New York bash in a private jet, not because she sought privacy but instead because of her craving for nicotine.
The Mail on Sunday quoted a source as saying:
She and Michael both smoke, and Catherine enjoys a cigarette when she flies, so a private jet is the only way she can smoke on board as it’s banned on major airlines. She’s quite a nervous flyer and it’s the one luxury she indulges in.
