We were all set to praise David Cook's performance last night, but first we need to report on the fact that the American Idol favorite was actually hospitalized after his Dolly Parton rendition.

He felt heart palpitations and was treated for high blood pressure. Fortunately, Cook was released back to the American Idol apartments where he was "doing fine," a source confirms.

As for his pre-hospital singing: Cook once again impressed the judges with a stylish version of Parton's "Little Sparrow." He looked healthy during the performance and we wish David Cook a full recovery.
