In the footage, Beyoncé 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.'

Beyoncé 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.'

Beyoncé's new video comes after it was revealed that Justin Bieber, Lady Gaga and Michelle Obama are among the famous faces who have signed on to support the singer and the global campaign for World Humanitarian Day.

The campaign asks that today people help others through such acts as making sandwiches for the homeless or volunteering at a local charity. The goal is to share 1 billion messages of hope.

A representative for Beyonce says that Bieber, Gaga, Obama, Rihanna, Shakira, Jay-Z, Gwyneth Paltrow, Chris Martin and others will participate.
