Katy Perry has been showing us how to live the single life in style this week. Not only has the star popped up at a number of events from the 2013 Delete Blood Centre Gala to the Catherine Martin and Miuccia Prada Great Gatsby exhibition opening cocktail party wearing designers including Vera Wang, Bottega Veneta and Giambattista Valli, she's also got a very high profile new shopping companion. The singer shared a photo of herself hitting the boutiques beside a stylish, silver haired man along with the caption: "Today my friend Tommy Hilfiger took me shoe shopping #kingofclassic". We're desperate to know what footwear fancies Miss Perry bought.
Meanwhile KP's friend Rihanna has arrived in Montreal for the Canadian leg of her Diamonds World Tour. The singer is seen sitting at the side of a busy road with her entourage wearing printed leggings, a grey hoodie and white trainers, teamed with an obligatory backwards cap. This is a very casual look for RiRi who has posted a lot of glam outfit pics recently from a Mary Katrantzou dress and Tom Ford heels to a Givenchy t-shirt.
And finally, everyone who's anyone has been flocking to Beyoncé's Mrs Carter World Tour shows at London's O2 arena. Reality star Kim Kardashian left her Greek family holiday to hang out with Bey's mum Tina Knowles backstage while supermodel Cara Delevingne got a fantastic view of the performance which we assume she attended with her pal Rita Ora who is signed to the bootylicious singer's hubby Jay-Z's Roc Nation record label.
