Coco Brown
All Star
Her first single was with paul wall and she effectively made grills immediately corny at a time when it was popular
And it also showed why the OP is dead wrong for even attempting a Britney comparison. Neither of them can sing but prime Brit was a great entertainer (she's still good but sometimes she def phones it in). Brooke can't sing, she can't dance, it's just blah and bad all around lol
