A video of the 'Love On Top' singer performing track 'I Was Here' live at World Humanitarian Day has emerged online, following news of her involvement with the cause earlier the month.

Last week Beyoncé spoke of the positive influence she wanted the song to have, saying she wished to leave her mark on the world.

Last week the 'Countdown' star unveiled a number of pictures from her private family album, including shots of her and husband Jay-Z and baby Blue Ivy.
