Catherine Zeta-Jones(01 of17)
Open Image ModalThere's strong hat game here from Catherine, she also gets bonus points for the retro sleigh. The thing is, celebs always look like they're posing don't they? Instead of having *actual* fun. So... How enforced is the smile? 6. You see, this picture gives the illusion that the Welsh actress is FLYING down the hill, but she evidently isn't because her hair isn't all over the place. Nothing gets past us. (credit:PA)
Hugh Jackman(02 of17)
Open Image ModalLook... there's a ball joke to be made here, isn't there? Luckily, we're better than that. How enforced is the smile? 1. How could anyone clutching a ball that big be sad? We'd love to see a shot taken just seconds after, once it'd had been thrown though. (credit:Big)
Craig Revel-Horwood(03 of17)
Open Image ModalOh Craig, never change. How enforced is the smile? 8/10. Craig has joggers on, there's no way he could be genuinely happy. (credit:WENN)
Geri Halliwell(04 of17)
Open Image ModalWe're loving the jacket - but it'd be better if it was Union Jack print, dontcha think?How enforced is the smile? 7/10. Does Geri even know how to ski? This is the face of a person who's trying their luck. (credit:Big)
Kate Moss and Jamie Hince(05 of17)
Open Image ModalAh, Mossy and Jamie, back in their days of wedded bliss. How enforced are their smiles? Not very. Neither of them are trying *that* hard, and Mossy seems to be putting more effort into her pose, which we're a big fan of. (credit:Big)
Lily Allen(06 of17)
Open Image ModalThis is, without a doubt, the strongest hat so far, nice work Lily.How enforced is the smile? Quite. We'll give this one a 7.
Graham Norton(07 of17)
Open Image ModalAs pictures of celebrities in the snow go, this is a reasonably poor effort, but Graham's dogs are just the best. How enforced is the smile? 0. There is no smile to rate here. (credit:Big)
Mischa Barton(08 of17)
Open Image ModalMischa's wisely concentrating on the skiing at hand. Nicely done. How enforced is the smile? Once again, we find ourselves with no false Christmas cheer to evaluate. NEXT. (credit:Big)
Susan Boyle(09 of17)
Open Image ModalAMAZING. How enforced is the smile? Not at all. What. A. Woman. (credit:Big)
Victoria Beckham(10 of17)
Open Image ModalWhat she's lacking in the festive cheer stakes, VB is more than making up for when it comes to style. How enforced is the smile? Posh Spice? Smile? You've got to be kidding. (credit:Rex)
Paris Hilton(11 of17)
Open Image ModalParis is a pro on the slopes. How enforced is the smile? 9. Could definitely do better. (credit:Big Pictures)
Arnold Schwarzenegger (12 of17)
Open Image ModalWhat. A. Man. How enforced is the smile? He may not be grinning, but we reckon Arnold is definitely enjoying himself, so he gets a free pass. (credit:WENN)
John Snow(13 of17)
Open Image ModalSorry, we couldn't resist. (credit:Jo Hale via Getty Images)
Heather Mills(14 of17)
Open Image ModalHeather's competing days are no behind her, but isn't this a lovely pic?How enforced is the smile? Given that Heather was competing at a national level when this snap was taken, we reckon it's a 1/10 on the fake grin front. (credit:Martin Schalk via Getty Images)
Kanye West(15 of17)
Open Image ModalOh Kanye, don't ever change. How enforced is the smile? We shall never know. *strokes moustache* (credit:Splash News)

Gwen Stefani(17 of17)
