Here is how difficult of a night it was to assess on American Idol on Tuesday: Lauren Alaina gave both the best and the worst performance.

Dedicating a cover of Martina McBride's "Anyway" to victims of the recent tornadoes in Alabama, the aspiring country star nailed every note and every emotion during her first time on stage, causing self-proclaimed heartbreak for Steven Tyler.

See what we mean here:

However, Alaina's follow-up attempt to act sassy during a version of "Trouble" came across as forced. Tyler admitted he wasn't sure if she pulled it off.

Scotty McCreery had an equally uneven evening, bringing tears to the eyes of viewers with the post 9/11 ballad "Where Were You (When the World Stopped Turning)," yet getting overly hokey with an odd rendition of "Young Blood."

James Durbin was probably the most consistent, though neither "Don't Stop Believing" nor "Love Potion No. 9" would be included in his top performances of the season.

Finally, Haley Reinhart had her song choice questioned after selecting Michael Jackson's "Earth Song," but rebounded with what J. Lo dubbed one of the "best performances of the year" with "I Who Have Nothing."

Who is going home this week? Talk about a tough call! We'll say Haley. How about you?
