The Grammys were full of controversy this year - from Adele's re-do of her George Michael tribute to Rihanna taking her own hip flask to the awards, the ceremony was not short of a raised eyebrow or two. But eyebrows were raised no higher than when Adele’s 25 beat Beyoncé’s Lemonade in the Album of the Year category with Adele herself saying she couldn’t accept the award.

Solange KnowlesSolange Knowles has hit out at the Grammys over their snub of her sister's album, Lemonade

And now Beyoncé’s sister Solange has come out to criticise the snub of her big sister at the awards.

The 30-year-old singer took to Twitter to express her disdain at the underappreciation of black artists shown by the Grammys and said: "There have only been two black winners in the last 20 years for Album Of The Year.

"There have been over 200 black [artists] who have performed.

"Create your own committees, build your own institutions, give your friends awards, award yourself, and be the gold you wanna hold my g’s."

Despite the fact she had since deleted the tweet, Solange had previously shared a Tumblr post from Frank Ocean in which he accused the record academy of "cultural bias".

On the night itself Adele, who also took home four more awards, asked "what the f*ck" Beyoncé had to do to win the award.

Before eventually breaking the award to share with her idol, the London-born star said: "The ‘Lemonade’ album was so monumental, Beyoncé, and so well thought out and so beautiful and soul-bearing, and we all got to see another side to you that we don’t always let us see.

"All us artists here, we fucking adore you. You are our light, and the way that you make me and my friends feel, the way you make my black friends feel is empowering, and you make them stand up for themselves."
