In recent days, Beyonce has spoken out in support of the Black Lives Matter movement following the death of George Floyd in Minneapolis.

The Grammy-winning star - who is married to rapper Jay Z - urged people to stay "aligned and focused" in their battle for "real justice".

Alongside an aerial photo taken of protesters in Minneapolis, the 'Formation' singer wrote on Instagram: "The world came together for George Floyd.

"We know there is a long road ahead.

"Let's remain aligned and focused in our call for real justice."

Prior to that, Beyonce revealed she felt "broken and disgusted" by Floyd's death.

She said: "We all witnessed his murder in broad daylight. We're broken and we're disgusted. We cannot normalise this pain.

"I'm not only speaking to people of colour. If you're white, black, brown, or anything in-between, I'm sure you feel hopeless about the racism going on in America right now."
