The day also saw a surprise from Rachel Chinouriri on the BBC Introducing Stage, who was only revealed as Friday's stage headliner in the morning.

She played songs from her recent debut album What A Devastating Turn Of Events.

"Me and my friends, we're quite good at keeping secrets. I'm a Scorpio so quite secretive," Rachel told Newsbeat.

For most of the day, though, she was "hiding in the traffic", in a journey that ended up taking her four hours.

The New Music Stage saw the likes of Diplo and Kenya Grace perform too.

But one group who didn't perform were Girls Don't Sync, who posted on Instagram that they pulled out due to "timing" issues.

There are expected to be about 100,000 people attending across the three days of the Radio 1 festival.

The rest of the weekend will see Raye headline on Saturday, and Coldplay on Sunday.

Aitch, Griff and Mabel will be playing the Main Stage on Saturday.

Sabrina Carpenter, Olly Alexander and Vampire Weekend will also hit the Main Stage on the final day of the festival.
