Alicia Keys has explained the reason why the video for her collaboration with Beyoncé never saw the light of day.

'Put It In A Love Song,' the track she recorded with the former Destiny’s Child star for 2009’s 'The Element of Freedom,' was initially intended to be a single. But after it was pulled from the release schedule, the promo was never unveiled to the public. 

Keys told Essence magazine: "Sometimes with creative things [it] all comes together and it's [perfect], and sometimes things almost come together and it's better to just leave it.”

But the 31-year-old, who releases fifth album, 'Girl On Fire,' in November, added that she still enjoyed the experience of working with the ‘Crazy In Love’ hitmaker:

"We had a ball shooting the video. It just so happens that the whole thing, for some reason or another, didn't quite come together, so we just decided to leave it."
