One of the most famous brazilian pop singers is Wanessa Camargo.. I really dislike her, but I'll post a video of her since her new song is a cover of Dixie Chicks' Not Ready To Make Nice and you may know it..
Wanessa Camargo - Não Tô Pronta Pra Perdoar
One of the two options. Either the Dixie Chicks went crazy by letting her do this cover, or Wanessa's management offered a hell lot of money to them. haha.
