It was a big weekend in the UK with London not only playing home to the Wimbledon finals, but also the Barclaycard Wireless Festival at Hyde Park. The line-up included Rihanna, Nicki Minaj, Jessie J and Rita Ora making it a double whammy of great hits — and great nails. From an ombré manicure in moody grey which we spotted on Rita Ora to Rihanna's dipped-in-molten-gold to Jessie J's demure baby pink talons, it's the perfect place to draw inspiration from.
