Instagram's CEO and founder Kevin Systrom and celebrity chef Jamie Oliver threw an exclusive, invite-only party in London on Monday night at a venue in the shadow of St. Paul's Cathedral.
It's the second annual party the photo app has thrown in the UK, which aims to celebrate all the Instagram stars that have made it such a success in the region. It's as much a marketing exercise as it is a celebration. Celebrities turned up in their droves. And Instagram made sure they were snapped.
The biggest star in attendance was One Direction's Liam Payne. He's an active Instagrammer who caused a social media storm among 1D fans last year when he launched his account under the name @fakeliampayne.
Here he is posing with Kevin Systrom last night:
