Pop star Dua Lipa, Caroline Flack and Princess Beatrice are among the A-list attendees at the British Summer Time concerts in London's Hyde Park.
This year's headliners included Celine Dion and Stevie Wonder.
Lipa opted for a casual look consisting of a baseball jacket and chunky gold jewellery as she attended one of the concerts, while Beatrice wore a navy blue shirt dress adorned with a white bird.
TV presenter Flack meanwhile, chose an olive green blazer, which she wore over a leopard print mini dress.
London mayor Sadiq Khan made an appearance in a navy blue suit, while singer Sam Smith arrived to watch Celine Dion wearing a black v-neck shirt.
Smith later posted a video on Instagram of himself and a friend fawning over the Canadian singer's performance.
