Solange
This performance was great, she sang nearly the first verse practically a capella and at about 3:21, some random person gets on stage and what does she do?
She dances with him LMAO and then when security try to get him off, she tells them to let him stay
I love her attitude and this song deserved so more success than it has got
Watched the video on CL just for the laughs, since i've never been into her. But she showed such good character that I might actually give her a listen.
