ABOVE: Kirstie Alley and partner Maksim Chmerkovskiy enter the Dancing With the Stars ballroom in last night's season premiere. Did you watch? Do you have a favorite yet? I, for one, couldn't believe how many times Wendy Williams cried — or how well Kirstie did! [ABC]

In TV News...

  • Major Office scoop: Not only will Ricky Gervais appear on the show again before the season is over, but Will Arnett will guest star in the season finale. How excited would you be if Will Arnett took Michael Scott's place? The only question that remains is whether he'll be playing a tough boss (like in Todd Margaret) or an idiotic, Gob-like character. Either way, it's a win. [Inside TV]
  • Speaking of NBC shows,Perfect Couples is being replaced midseason (with two episodes left to go) by — get this — The Paul Reiser Show. I'm sorry, what year is it again? [Warming Glow]
  • Helen Mirren will host Saturday Night Live on April 9th—with musical guest, the Foo Fighters! We look forward to what the Dame showing off her comedic chops. [TV Squad]
  • Tommy Lee will get his very-own show on SyFy called Culture Shock With Tommy Lee. More to come... when we figure out what in the world this show will be about. Our guess? Different — shocking — cultures. [TV Squad]
  • Reportedly, Jeff Daniels is in talks play a news anchor in Aaron Sorkin's new HBO pilot. [Deadline]
  • Did You Know: You can purchase shirts inspired by last week's Parks and Recreation that say "I met Lil' Sebastian at the Pawnee Harvest Festival." [NBC Universal]
  • The presenters for Comedy Central's Comedy Awards have been announced, as has the first recipient of the "Comedy Icon" Award: Eddie Murphy. [Splitsider]
  • Josh Holloway spoke about working with the cast of Community: "They're really tight with their comedy. It's rhythmic. It makes me feel so not very funny being around them. I was a little like, 'Uh oh. I'm not funny. I've got no rhythm.' But it worked out." I bet it did. [TV Overmind]
  • This is what every episode of Undercover Boss is like. [Best Week Ever]
  • Shannen Doherty and Danny Bonaduce will both star in SyFy original movies. We're imaging Shannen, as 90210's Brenda, dressed in flannel and screaming in some kind of 90s sci-fi film. (It will probably be nothing like that.) [TV Guide]
  • NBC has announced their Summer schedule, and you had best start preparing yourself for a lot of Jerry Seinfeld and America's Got Talent now, because that's about all you're going to get, in terms of new programming. [NBC]

Around the Web...

  • A handy guide to figuring out who all of thosecomedians in commercials are. Like the funny guy in the Verizon commercials that looks oh-so familiar, but you can't quite place him? Wonder no more. [Splitsider]
  • I got a good laugh out of this one: Microsoft Word introduces the "squiggly blue line" to alert writers when a word is too obscure for the masses. [The Onion]
  • It's a fight: Zooey Deschanel versus E! News' remarks about her face in a Rimmel London ad. E! said she looked photoshopped, Zooey disagreed. [Movieline]
  • Six things Rebecca Black has taught me. (Well, not me, but the author of the piece. Who knew Rebecca Black could be educational?) [The Hairpin]
  • Did you know that Bill Hader writes for South Park? Well, he does — and here he talks about the show's unique writing process that goes on with Matt and Trey. [Splitsider]
  • I guess Justin Bieber punk'd Willow Smith at a recent concert? I don't know, I feel old just saying those two names together in the same sentence! [Just So You Know]
  • Randy Quaid's got a new single and it's.... interesting. [Vulture]
  • Watch Jens Lekman perform two new songs! [Stereogum]
  • In case you haven't heard the news yet, AOL is folding 30 brands into Huffington Post sites—including Gawker.TV favorites Urlesque and TV Squad. So not cool. [Forbes]
