Bella Hadid, Rihanna and Cara Delevingne lead stars observing Black Out Tuesday

A number of celebrities have backed the Black Lives Matter movement by observing a social media Black Out Tuesday, in which they posted a plain black square and  removed themselves from social platforms for the day. 

Led by celebrities including Rihanna, Bella Hadid and Cara Delevingne, the day-long blackout – which was initially intended to be just for the music industry – swept Instagram as stars marked the day with a plain square posted on their grid.

The movement comes after the death of African-American George Floyd, 46, last week, who died in Minneapolis after Minneapolis Police Department (MPD) officer Derek Chauvin knelt on his neck for over eight minutes before he died from asphyxiation.

A medical examiner’s office on Monday ruled that Floyd’s death was a homicide as they appeared to walk back initial reports that he wasn’t strangled.

The examiner’s findings that the death was a homicide by asphyxiation confirmed the same conclusion of the independent autopsy that was also released on Monday, but there are key differences over the cause.

Chauvin, who is white and was fired from the Minneapolis police department over the incident, has been charged with third-degree murder and manslaughter, over Floyd’s death roiled the nation, which has sparked mass protests against police brutality across the nation.

The Black Lives Matter movement, which was first founded in 2013 following the acquittal of George Zimmerman and was nationally recognized for its involvement in the Ferguson protests in 2014 has been galvanized once more following the death of Floyd.

On Monday, it was announced that the music industry would observe the blackout in solidarity with the Black Live Matter movement, but it swiftly spread across the board with many celebrities and social media users taking part.

She wrote: ‘Instead of blackout, only highlight black activists, educational content, donation information, and imagery that depicts the truth of the protests’.

She further detailed why she would not partake, as she added: ‘I’m personally not engaging in the blackout but at the very least let’s be careful of doing this…

‘It was supposed to just be for the music industry but has caught on at the worst time. We need information, education and donation…

‘Thank you to my friends for educating me about a better way to be helpful, by sharing the work and words of black activists and writers and by instructing my followers how to be of service to the movement for black lives. #blacklivesmatter’/
