The fill-in managed to survive Wednesday night's elimination round, but Smith's rendition of "I Want You Back" on Tuesday night was deemed "horrible" by judge Simon Cowell.
Still, Smith hung on. Lindsay Cardinale, a 20-year-old university student from Ponchatoula, La, wasn't so lucky. Her rendition of "Knock on Wood" inspired Cowell to knock her with the words, "I think 30 million TV sets in America had their volume turned down simultaneously."
The show opened with all dozen contestants singing "When You Tell Me That You Love Me."
The fourth season finale is scheduled for May 24-25, at which point one of the singers will be awarded a $1 million recording contract. Before then, one more earnest hopeful will get the boot next week.
