This is a pivotal week for "American Idol" fans. After all:
-- Today is Allison Iraheta's 17th birthday. For those of you waiting patiently, she's now a year from being a consenting adult.
-- Tuesday is "Rat Pack" night, with the remaining contestants singing songs done by Frank Sinatra, Dean Martin or Sammy Davis. They could also do the music of Joey Bishop or Peter Lawford, but I wouldn't advise it.
