Betty White And 'Iron Man 2' Dominate The 'Late Night Lineup'

Once again, the biggest splash in late night this week was made by a guy who doesn't currently have a show, as the talk show universe is buzzing about Conan O'Brien's appearance on "60 Minutes." During that show's cornerstone segment, O'Brien described the end of his run on "The Tonight Show" as "a marriage breaking up," though he insisted that he didn't get "screwed" ("I went through some stuff, and I got very depressed at times," he said. "When we started putting this tour together, I started to feel better almost immediately."

As O'Brien's tour soldiers on and anticipation builds for his return to the late night scene on TBS in November, the rest of the network shows continue to deliver in the present tense. With a load of high-profile albums and big summer blockbusters on the horizon, now is the time to be staying up past your bedtime to check out what's up on late night. Take "The Late Show with David Letterman," which this week will feature latest "American Idol" castoff Siobhan Magnus (Monday, May 3), a performance by Sharon Jones and the Dap Kings (Tuesday, May 4) and buzzy-heavy rapper Wale (Friday, May 7). Over on "The Tonight Show," Jay Leno will counter with "Iron Man 2" director Jon Favreau on Monday, star Robert Downey, Jr. on Wednesday (May 5) and ESPN personality/"Dancing With the Stars" contestant Erin Andrews on Friday.

As usual, the two men named Jimmy will battle for musical supremacy, as Kimmel has Two Door Cinema Club (Monday), Godsmack (Wednesday) and Angels & Airwaves (Thursday, May 6). Meanwhile, Fallon will feature performances from Corinne Bailey Rae (Monday), OK Go (Tuesday) and New Pornographers (Wednesday). Fallon will also talk to "Saturday Night Live" host Betty White on Thursday, bringing back around part of the meme that Fallon helped start with his beer pong game with the actress last year. (It's also worth checking out "The Late Late Show with Craig Ferguson" this Thursday, as he'll have a performance from excellent new band Local Natives.)

In fact, White will compete with the stars of "Iron Man 2" for the most couch time this week, as she will also appear on "Today" and "Live with Regis and Kelly" this week.

Which are you more looking forward to this weekend: "Iron Man 2" or "Saturday Night Live" starring Betty White and Jay-Z? Let us know in the comments!
