Lauren Alaina may not get her shot to be the next "American Idol" because she has lost her voice ...spies on the set tell TMZ ... and it could be the break of a lifetime for Haley Reinhart.
We're told during the rehearsal this afternoon, Lauren -- who has been losing her voice -- was supposed to sing three songs. She got through the first, struggled through the second and was unable to perform the third.
Our spies say a doctor on the set has ordered Lauren not to sing or speak, but there is a "real possibility" she will not be able to perform on tonight's show.
We're told if Lauren is unable to perform, producers will reinstate the third place finisher -- Haley Reinhart who will then compete against Scotty McCreery for the title.
Producers are trying to find Haley right now.
