During an interview with Anne Hathaway on “Late Show,” David Letterman may have spoiled the already controversial ending of “The Dark Knight Rises,” unless you believe his subsequent backtracking comment that he is “kidding.” (Note: Don’t click the link unless you’re comfortable with “The Dark Knight Rises” maybe being spoiled for you . . . unless Letterman is kidding.)

Target will not sell the new CD by R&B artist Frank Ocean , but not because he has acknowledged publicly that he is gay; Target officials say they aren’t carrying the album because it was released first as an iTunes exclusive. (E! Online)

So “American Idol” is kind of imploding. Steven Tyler announced he’s leaving as a judge, Jennifer Lopez has basically done the same thing but is taking her sweet old time to make it official, and Randy Jackson reportedly may shift from judge into a mentoring role. If that happens, Mariah Carey could be tapped to become a judge. Because someone has to sit in a chair and tell aspiring singers they’re pitchy. (TV Column; Us Weekly)

Jezebel’s Lindy West gets in what should be the last series of words about Daniel Tosh’s ill-advised rape jokes but probably won’t be. (Jezebel)

The handsome Henry Cavill is scheduled to make his first official Superman appearance during Saturday’s “Man of Steel” panel at Comic-Con. But the L.A. Times’s Hero Complex wants to know: Does anyone still care about Superman? (Hero Complex)

Michael K. Williams of “The Wire” and, more recently, “Community,” reportedly maintained a sense of calm at Atlantic City’s Revel nightclub last weekend when a fire alarm accidentally sounded.

Grantland’s Alex Pappademas breaks down the “Keeping Up With the Kardashians” episode that reveals Kanye West as Kim Kardashian’s maybe boyfriend. And it’s so worth a read. An excerpt: “As a doggedly cynical hate-watcher of this show, I long to agree with the people who think the whole Kanye-Kim thing is a baldly bogus PR/ratings stunt, conceptualized in a top-secret dry-erase-board summit meeting by high-ranking executives from Ryan Seacrest Productions, E!, G.O.O.D. Music, and the Illuminati, just like Kim’s marriage to Kris Humphries, the “leak” of her sex tape, and 9/11. At this point, there are probably people who believe in Santa Claus who understand that reality TV is just Blair Witch kabuki, and I want to be there with them, united in skepticism. But I can’t. There’s just too much on my heart right now, man.” (Grantland)
