This week in celebrity beauty Instagrams, we saw stars get ready for red carpets, runways shows, and Sundance premieres. Though temperatures are freezing in most places, these A-listers managed to look hot (thanks to a little help from their friends). Some highlights: Alexa Chung's Spring-ready floral nail art, January Jones's backstage beauty shot, and Joan Smalls's stunning cat-eye liner. See more of our favorite filtered photos, and don't forget to keep up with our editors by following POPSUGAR Beauty on Instagram!
