From red carpet premieres to just walking down the street, many a well-dressed celebrity has been out braving the cold.
Alexa Chung was out in New York launching her new range of jeans for AG in an all-white ensemble, a trend that is tipped to be this spring's hottest look.
Jennifer Lopez was also in New York donning an array of very warm looking fluffy coats, as she continued her promotion of her new film The Boy Next Door. We'd like to wear all of those coats right now please.
Finally, it wouldn't be right if we didn't mention Cara Delevingne, who was the guest of honour at last night's YSL make-up launch. Not only was she looking incredible, she brought her whole (very stylish) family along too.
