On Thursday's episode, the top 10 contestants - five from each gender - are expected to be named. Various online reports say that judges Randy Jackson, Jennifer Lopez and Steven Tyler will also choose "wild card" contestants to move on to the next round, although FOX has not confirmed this.
Thursday's show will also premiere Lopez's new music video for her dance song, "On the Floor." It is the debut single from her seventh studio album, "Love?," which is set to hit stores on April 19. (The date was recently postponed, and was originally set for March 29(.
