melody and nicole were in a group called eden's crush together before pussy cat dolls, mayb thats why she's there to support.nicole has been trained in dancing for forever so thats why shes good....idk why everybody is hating on trent sayin sumn that sounds negative about rihanna when nicole was bitchin abt the song like it was a fifty yr old jam. when you heard her bitch about it before they danced you never would have thought that it was rihanna's song. he has a right to his opinion and if he thinks that the singer for dwts sounded better than rihanna then so be it. aside from that, cuz she got signed at sixteen don't mean she can sing, case in point miley cyrus, marques houston, britney bitch, need i go on???? jus get over it or get off the damn site
