In the footage, Beyonc is seen wearing a gorgeous gown, with her long hair pulled back into a high ponytail, as she showcases her vocal talents on the soulful track.

The singing superstar revealed earlier this month that she would be dedicating the track to World Humanitarian Day, which is today.

She explained: ''It says, “I want to leave
my footprints in the sands of time” and it basically is all of our
dreams, I think. And that’s leaving our mark on the world. I feel like
we all want to know that our life meant something.

'We all have our purpose, and we all have our strengths…it
feels so wonderful to do something for someone else. And I think for
the U.N. to want to include the whole world was something important, and
I feel like that’s what I represent.'

Beyonc previously said about the charitable event: 'We all see the headlines
and we think what can I really do to help

'World Humanitarian Day is an opportunity for all of us to work together
to make a difference. This is our time to leave our mark on the world
and show that we were here and we care.'
