Singer Justin Bieber has vowed to "shine a light on racism", and says he will do his part to stand up and make sure everyone is equal.

Bieber, 23, took to his Instagram account to share his support for the Black Lives Matter movement. He says though he doesn't know what it's like to face the same struggles people of colour face, he will do his part to stand up and make sure everyone is equal.

The "Sorry" hitmaker posted an image of the Black Lives Matter logo and wrote: "I am a white Canadian and I will never know what it feels like to be an African American but what I do know is I am willing to stand up and use my voice to shine light on racism, because it's a real thing and it's more prevalent now than I have ever seen in my lifetime... We are all Gods children and we are all equal."
