This week Radio 1 DJ Nick Grimshaw stepped into the spotlight and invited his showbiz mates to help kick-start his breakfast show. We've loved looking at snaps of Nick hanging out with the likes of Emma Watson and Alison Mosshart. Meanwhile Grimmy’s bessie Alexa Chung is back in New York but she still sent us into a style frenzy with Instagram pics including a snap of herself wearing a Valentino jumpsuit. Models Cara Delevingne and Alessandra Ambrosio posted some off-duty poses and Kelly Osbourne reported live from the Emmy Awards red carpet. But our favourite pic of the week has to go to Kim Kardashian who did her best impression of her mum Kris Jenner. We wonder what Kanye thinks of the transformation!
