American Idol

Will one of two mistakes cost one of the women a spot on the American Idol finale next week?

First, Haley Reinhart actually tripped over a set of stairs during her rendition of Led Zeppelin's "What Is and What Should Never Be," but the mishap may have just made the performance even more memorable. The same can be said of her dad on the guitar, as seen below:

After the ovation died down, Randy told Haley she was "slaying it," which doesn't bode well for Lauren Alaina. That contestant actually flubbed a key change during a cover of "If I Die Young." J. Lo kindly referred to it as an "honest moment."

But will it spell the end of Lauren's run?

Scotty McCreery seems like a sure thing for at least one finale slot, following a trio of strong performances. They highlighted by "She Believes in Me," a track that incorporated a piano and a string section and a chorus that led to Steven Tyler remarking: "You put it over the top for me just now."

How about you? Who do you think is going home tonight?
