With the notable exception of, well, any episode of Mad Men, a prominent Hollywood actress smoking on television, or in public for that matter, is a rarity. Particularly during a live network broadcast awards show.

Yet there was Julia Louis Dreyfus, blithely puffing away during last week's Golden Globes ceremony (pictured). Her sunglasses and steely demeanour implied she was gently mocking the late Elizabeth Taylor. More notable was the fact  Dreyfus was not sucking on an old-fashioned dart, but an electronic device known as an e-cigarette.
