You might be surprised to know that champagne is actually not that bad for you -- compared to other alcohols, of course. A glass of champagne has 90 calories, compared to 205 in a pint of beer and 740 in a margarita. Not bad, eh? Drink the whole bottle and you're looking at about 500 calories, but we don't recommend that for reasons other than the calorie content (public humiliation is never a good thing).

So ignore what Carey said and enjoy a glass or two this holiday season. Unless, of course, you're pregnant like Mariah is rumoured to be.
