A mixed week on the style front, with Amanda Seyfried brazenly stepping into Mila Kunis' heels to stand next to Justin Timberlake on red carpets in cities across the globe whilst promoting a film that will probably be forgotten long before she's lived down her Jimmy Krankie suit.

Taking a break out of her busy telling-Gary-Barlow-off schedule, Sinead O’Connor has shaved her head, put on a nice dress and attended the amfAR Inspiration Gala in Hollywood, where she bumped into Debbie Harry and Sean Penn.
