Bet you didn't know it's National Cupcake Week? It'd just be rude not to take advantage - even Taylor Swift is getting in on the baking action. The singer Vine-d a video last night of what she could only describe as a 'massive baking day.' Models Karlie Kloss and Jourdan Dunn are all over the sugar and sprinkles, too. So what's left to say? Pass us an apron and pre-heat the oven to 180. Ready, set, bake!
