In case you hadn't noticed, celebs are going crazy for nail art, tweeting and Instagramming pics of their latest nail designs all over the shop (which is a nice idea but in reality there is no way we would be able to remotely copy them and actually get them to look nice). And the latest lady in line? Katy Perry with her cute cartoon nails. Yesterday before she walked the red carpet for the premiere of her movie, Katy Perry: Part Of Me, in Tokyo (about time too), @katyperry tweeted: "It doesn't get any better than hand painted DARIA nails by the girls at ES Nails TOKYO!" For those of you who don't know, Daria is an animated TV series from the late 1990s about a teenage girl who feels she's an outsider. Reminiscent of anyone, Katy? (That's not a dig by the way, watch the film!) Ms Perry also wore a cloud-print mini dress and amazing purple statement heels.
