Is Jennifer Lopez the Marilu Henner of "American Idol"? Henner, as we learned from "60 Minutes" last month, remembers every day of her life in detail. Lopez, for her part, claims to have remembered an "Idol" contestant named Rachel from Season 6 who was cut early in Hollywood Week. When she reappeared at this season's auditions -- which began airing tonight -- Lopez, who's been watching the show for 10 years, said she recognized her. And put her through more on the strength of her previous audition than on her rendition of "Hallelujah." Color me impressed. I can't even remember Rachel's last name.
