Top two contestant Lauren Alaina was cleared to perform on tonight's episode of "American Idol" despite having problems with her voice prior to tonight's taping. A doctor examined Lauren earlier today and concluded that she would be able to perform on tonight's episode.

During rehearsals today, Lauren had noted problems with her voice and a source from "American Idol" said that Haley Reinhart was on stage rehearsing for tonight's show just in case she had to perform in place of Lauren.

Lauren is up against finalist Scotty McCreery tonight for this season's title.
