Niall Horan with Conor Maynard
Niall Horan from One Direction was enjoying the music with a bunch of friends. 'We camped last night (Saturday). It was wicked but so, so hot. I wasn't really drinking before - I only had a couple of pints - but when I woke up, I was the most dehydrated I've ever been!'
As for his favourite acts of the weekend, 'I've been to see Rita Ora, I love her,' he told us. 'It is difficult getting through the crowds but I've got two big bodyguards and I just have to say sorry, I can't have photos today. I'm on my day off!'
Of course, we couldn't miss the chance to ask him about the band's amaze appearance at the Olympics Closing Ceremony. 'It was really exciting. No one knew we were going to be there apart from people who kind of guessed on Twitter.'
So what's next for the 1D boys? 'We're really busy at the moment, shooting a video this week but this is my one day off'
Niall's band mates Louis Tomlinson and Liam Payne were also spotted soaking up the atmosphere with their gorge girlfriends.
