And whilst many have praised the star for the song's catchy beat and the video's fun and playful look, others have berated the singer for her 'immaturity'.
"Charley all this they show say you they love da nigga, move on cos this be childish", wrote one fan whilst another added "You need to get a life this is childish."
Is this the last we see of Derby's attempt to drag her sweet ex's name through the mud?
