Rita Ora and Ed Sheeran collaborated on 'Your Song' after he sent her a demo of the track.
The 26-year-old singer is open to working with other musicians, and Rita was delighted when her long-time friend reached out when he heard she was working on her upcoming album.
Speaking to Tom Green at the KISS House Party Live at the SSE Arena, Wembley in London, Rita said: "We were friends for a long time, since we were 16. We had the same management before we released any music.
"He asked if I was still making my album, and he sent me a demo. I thought it was crazy great."
Previously, Rita claimed "fate" helped make her Chris Brown collaboration 'Body of Me' possible when they ended up in the same studio session.
The British singer had already reached out to Chris through his direct messages on social media, and it made approaching him for the 2015 song so simple.
Rita explained: "It wasn't to hook up with someone, it was for a collaboration. I wanted to work with Chris Brown, so I sent him 'Body On Me'. That's what's so great about DMing.
"Then we were in the same studio session, and it was fate. So I walked in there and said you need to be on my song."
Meanwhile, Rita recently discussed the differences between making her highly anticipated second album - which is due out in March 2018 - and her 2012 debut 'Ora'.
She shared: "[It was a question of] who can contribute; hey, everyone, let's jump in the basket.
"It definitely wasn't how I thought albums were meant to be made. And now I see I was right: they're not meant to be made like that."
