Who's the girl that sings in right round with flo rida
I think is Sia Furler. She also did "Wild Ones" and "I Cry" (though that one was sampled from an old song, she just pantomimed.)Correction: other sites say Ke$ha, though she was uncredited.
The song "Right Round" by Flo Rida features Ke$ha.
It was the song that got Ke$ha her start. She wanted a contract so she just walked into the studio and he asked her to be on the track.
