Beyoncè teased a video on her Instagram account that turned out to be a trailer for a secret HBO project called “Lemonade”. During the minute-long clip, the singer, who is is seen wearing a fur jacket with braids, says: “The past and the present merge to meet us here”. But what is “Lemonade”? Is it a concept album, a new single or a TV drama in which Queen Bey plays a role? Fortunately, the wait’s nearly over — Beyoncé announced that “Lemonade” will premiere on HBO on April 23.
